What is the Deal - My wife?

I have been separated from my wife for about two months. In the months of March and April we have been back and forth. We have been co-existing fore the past couple of years. No infidelity of my knowledge. She stated she was lonely and smothered. She needed space. I left in May.We have a blended family my stepson is disrespectful and manipulative and the reason I am out of the house I do believe because my wife protects him. Make a long story short. After May 6th my wife wasn't wearing her ring. I asked her on May 9th if she still wears her ring and she says yes, that she forgets to put it on when she sees home health care clients. I dropped my daughter off and still not wearing the ring, I asked here and she says why are you nitpicking and we left it at that.On the 16th I dropped my daughter off and tried to kiss her and she says that isn't happening. She let me hug her but no kiss. I called later and asked her were we done and she said we haven't had a connection for the past couple of years. That she prays about it because she doesn't want to make a decision out of haste. She says I don't respect her boundaries or her feelings. I asked here the next time we see each other if she would pray with me and she agreed. I also stated I would respect her boundaries, and asked her how much she wanted me to call. She said that was up to me, that when I call I drill her (which is true) out of suspicion. Thursday we prayed and after the amen she quietly said umm..hummm. So Friday I called and asked her if there is any possibility that we can re-establish our connection? Her response was I can't answer that right now, answering that would be making a decision that it is over. I expressed to her that I pray the that she releases that anger. The anger is from other relationships too in my opinion. I haven't committed adultery, abuse her, or drink or smoke. I always come home. I am guilty of not spending time. Both our needs weren't being met. My friends seem to think this is a control thing and she deliberately doesn't wear the ring. My wife appears to be a needy person. I don't know. What do you think is there hope or does she want me to end it, because she doesn't want too. What should I do. Give me your take. Peace
