Agree with advice given so far and encourage you to talk this over with your Pastor. I am sure once they know how hard this is for you they will be understanding and support you.
Regarding your wife, people usually put others down and critisise because their self-esteem has been damaged and their sense of self-worth. So in order to make themselves feel better they put others down.
It seems like your dear wife has some unresolved issues and these may be painful to face. Issues from as long back as her childhood.
She may have buried things that were too hard for her to face or deal with. Or just did not have the opportunity to receive the right kind of help and prayer support. So may not be fully aware of why she is how she is. But denial of a problem is common amongst those who need healing from emotional pain. It can be pretty scary to admit "weakness" as it can cause you to feel vulnerable. Just like in the past when you were hurt.
Also equally true is she may not know what is the "root" of her behaviour. This is where prayer and counsel can help.
The fact she needs to feel in control is evidence she is insecure. And insecurity can cause fear.
Her habit of lying, has become that ,a habit. Based on unmet needs and unhealed emotions. Jesus wants to free her from this and will.
I feel she behaves this way because some time in her past she suffered rejection and this can cause people to feel the need to be in control of everything.
It's so sad you have let her insecurity cause you to not keep contact with new friends. That would not have helped her or you. Next time you have that opportunity then continue with the friendship.That will enable you to discuss why it is unreasonable for her to prevent you having friends and open the door for her to say why she feels so threatened by them.
Don't let her insecurity manipulate or control what you want to do. She needs help yes, but you shouldn't suffer because of it. Otherwise the enemy could use this to cause you to become resentful over lost ministry opportunites etc
She needs to find her security in the Lord and this could take a while. Meanwhile show her lots of love and patience, as indeed you are doing. But make it claer that she can not dominate your life by preventing you making friendships. That clearly is wrong and unhelpful to you and her recovery.
She needs to see that these friendships can enhance her life and not threaten anyway your love for her as a person.
She may not agree to this but I feel she needs you to make new friends. Ones so far she has put down and dissuaded you from having - so that she will have to face why she is so uncomfortable with that and therefore says what she does. It is only when people face upto their difficulties do they eventually realise it is them that need to change.
I appreciate doing this may be hard for you due her reaction but this cycle of " having to control things" from her, needs to be broken. You need to feel free to do what the Lord calls you to do and don't accept her preventing you from doing it.
I say all this not to upset you but because I care that both of you find much love and peace in the Lord.
And because once I was just like your wife, insecure and scared of my now ex-husband having friends. I was damaged through abuse and lost my sense of self-worth so you tend to have a negative view of yourself. In order to bolster yourself you can put others down unfairly. Thankfully I recognised what I was doing was wrong and felt so bad about it, so I stopped. And since then God has continued his healing.
What helped me was my ex-husband continued with new friendships despite my objections and over time when I realised what I said didn't make any difference, I accepted it. And as I let myself get to know them, they eventually became a source of blessing and not someone to fear or put down.I actually opened up to them and said what my problem was and they were so kind and loving and prayed for me. That was God's mercy and grace in action.
God enabled me to see people how He saw them and not from my own, damaged point of view.
I hope this has helped. There is hope and what I shared about still keeping friendships despite your wife's objections, was what long term helped me.
I will be praying for you both through this.
Be encouraged, God is faithful and will complete the work He has begun.
Much peace and blessing
