I've been there.-- Oh the misery!
First off, your post lacks self-respect, dignity. Maybe you're not thinking straight. You seem gentle and decent. But maybe you're
too familiar with abuse to flag it. Or mentally you're in a rough patch. Either way, not healthy. Also "Christian" is not a social status or privilege, actually the opposite.
Anyhow, what you've described is disrespect/violation of
boundaries, disrespect of your person, of the home, and it's psychological abuse, torture, insult, noise pollution, perhaps hygiene, invasion of privacy... You say "temptation" but it's leaning more on sexual harassment: Unsolicited/unwelcome sexual anything. Like a home invasion, minus the physical aggression or violence. --- Using these terms descriptively, not legally.
OK, so apart from prayer. You can neutralise the situation or go down the dispute path. Avoid going home, spend your life outside. Play loud music at home. Or fight fire with fire by inviting people over constantly for a stream of witnesses and buzz kills. lol. All fairly passive.
Otherwise, "
Open rebuke is better than secret love. Faithful are the wounds of a friend; but the kisses of an enemy are deceitful." (Pro 27:5-6) Confrontation: Speaking up, and often, won't hurt. Call it as you see it. "We talked about that. Please stop!"
If that fails. Dob. Neighbour, parents, minister, teacher, employer. It's a reasonable complaint. "So the bloke who's living with me is... Please help. For my sanity." Shines light on darkness. Shaming in hopes of response. Biblical dispute resolution is to confront with 2 or 3 witnesses. Matthew 18:15-17
As a rule, Scripture teaches to go from community to community, covenant to covenant. Parent's house > Own house/family. Single > Single or Single > Married. "Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh." (Gen 2:24) There are exceptions, economic/survival reasons, special mission. Fugitive on the run. Otherwise, it's a prodigal son scenario, rebellion, ingratitude, traitor. Absalom.
However, Biblical behaviour is only applicable and enforceable under a biblical household/family/church. Law of the land. Hence, subscription to the Ten Commandments that God commanded included sticking it on the front door, blessing all who enter, coming and going. But you forfeited those or any other privileges having left home, jumping into this arrangement, underestimating the intimacy of living with someone. "Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness?" (2 Cor 6:14)
So unless there's a higher power, a person in authority, who you can appeal to for help. You're stuck in the mud. Maybe the building manager, land lord, strata management, or 3rd party intervention (borrow a minister, justice of peace, a local doctor or similar -- someone neutral yet respectable) to speak up on your behalf. Gently but directly.
Only God can help you now and long term. --- PRAY for a way out. God promised "good tidings to the meek...
liberty to the captives ...to comfort all that mourn" (Isaiah 61) You're asking a forum for wisdom, but where is your personal responsibility? "Buy the truth, and sell it not; also wisdom, and instruction, and understanding." (Pro 23:23)
Secondly, what you need (and have always needed) is a kind and loving community (church/synagogue duty) to take you in and look after you the way your parents/family clearly didn't. Or maybe you need a stiff lesson, to learn from mistakes, I can't tell.
But you seem oblivious to basic boundaries, respect as a person, a creature of God, made in his image. Support: emotionally, spiritually, socially. Maybe you're at fault and have to make amends. If so, do that. But it sounds like a your cries tend to fall on deaf ears.
Not exactly fornication I know, but the principle is true: Run! Or just step out when they're around. Go to the park, read, grab a coffee, run, gym, etc.
"But he that is joined unto the Lord is one spirit.
Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body." (1 Cor 6:17-18) "Better is a dry morsel, and
quietness therewith, than an house full of sacrifices with strife." (Pro 17:1)
If that doesn't work: Cut and run! (brace yourself) "And if thy right hand offend thee, cut it off, and cast it from thee" (Mt 5:30)
Social break down is a terrible thing. I don't know about the US but in Sydney we have church or para-church organisations that work along side most church groups. To help homeless people, domestic violence cases, child abuse, etc, where the person has no where to go. There's also the state housing service (welfare state).
- Church services: Call all the churches in your area
- Family & Friends: Call everyone you know, for spare rooms, a couch
- Shelters: For homeless etc
- State services: Government housing
- House sitting jobs, for temporary accomodation
- Sleep in your car + gym membership for showers
- Tent in park or camp grounds: Backpacker style
Once you go down these routes there can be stigma and a mental/emotional health toll. Not for the faint hearted. Ultimately, you gotta toughen up, spiritually. Prayer, fasting, Scripture for starters. Keep your mind sharp.
