Its sad to say that I have noticed a far amount of those types of relationships going on round here.
A number of years ago, I had a few female freinds that pretty much had the requirements for someone to "date" them....No job, lives at home w/ parents, mootcher, alchololic, drug user, abbusive (mental and physical)....in other words just plain loosers.
IMO this problem is deeper than most people know. They are in fear that if said person were to leave that no one else would "love" them. Well those types of relationship do not have any love in the IMO.
1CO 13:4 Love is patient, love is kind and is not jealous; love does not brag and is not arrogant,
1CO 13:5 does not act unbecomingly; it does not seek its own, is not provoked, does not take into account a wrong suffered,
1CO 13:6 does not rejoice in unrighteousness, but rejoices with the truth;
1CO 13:7 bears all things, believes all things, hopes all things, endures all things.
1CO 13:8 Love never fails; but if there are gifts of prophecy, they will be done away; if there are tongues, they will cease; if there is knowledge, it will be done away.
That is TRUE love.
