Is there such a thing as QLC??? Please HELP!!!!!!

[BlindTEENA]

So during the last month in a half I have experienced the most pain; ever, in my life. My H initially said that he wanted to take a "step back" to re-evaluate things; this then turned into, "a Separation would probably be best right now." And now he's saying that he wants a divorce and that the "well has run dry."
I started noticing a change in his attitude about four months ago. During minor arguments he would threaten to walk away from the marriage or say things like, "well I don't really care" or "It's whatever!" He started making purchases without telling me, picked up overtime without discussing it with me, hanging out with friends more frequently and just all around avoiding being home. He seemed less happy to ba around and always seemed to be in a bad mood. Alot of the times he would purposely start arguments and try to get reactions out of me. He cnacelled on an event that he knew was VERY important to me and his reason for not going was, "he had to go to the gym."
This is clearly not the man that I married and sometimes I ask myself, "Why even fight for a person like this?" Bt I honestly don't think that this is him. He is definitely going through something and I am trying to be as patient as possible. I suspect that he may have been having an emotional affair and that this "separation" is so that it can become a PA. He tells me repeatedly that he is not in love with me anymore and that the well has run dry.
When he first dropped this bomb on me I cried, pleaded and try to convince him to change his mind and this worked for a short period of time. Since then I have backed off. I only text him regarding neccesay things, I don't call him at all. I have just been trying to work on me. going to the gym, focusing on school work, hanging out with friends, going to counseling etc.
I question whether or not being hopeful for reconciliation is more harmful than beneficial. He is currently staying at his moms house and recently called to say he wanted to come back home and that he feels like he may be "going through something." I actually told him that coming back home wasnt a good idea because it had only been three days since we were living separately and I knew that he was missing his apt and not me.
I'm glad that I was strong enough to say this because a few days later he starting talking about Divorce!!!! He goes back and forth but every 5 days or so he makes sure to reassure me that we are THROUGH and that he was completely unhappy. What's crazy is that I don't believe him; and I dont feel like Im being indenial rather his words and actions are completely irrational.
After he moved in with his mom he started calling and texting me excessively and popped up at the apt a few times unannounced. He even brought me dinner one night. I thought that my focusing on me was actually making him more interested in me. But then he flipped again
Also prior to him moving out; we were doing an in house separation which was extremely unhealthy for me. I told him that if he wanted to be separated he had to leave. 1 month was already too long. There were days when he would coe and watch tv with me, be intimate with me, talk with me etc (i would see glimpses of the old him) and then the next day or so he would come and tell me that "he doesnt want to get my hopes up" because he definitely wanted a separation. sigh
This is the most patient that I have ever been in my life. We are both 27; got married young (at 22) and I think that he wants to all of a sudden live the single, 27 yr old guy life. He's always been that perfect husband, never any problems or drama and now he wants to be a bachelor. I don't know what to do. I want my marriage to work but at the same time I have to have some respect and dignity for myself. Do I wait for him to "get it out of his system" and then just let him walk right back? Please help!!!!!!!!!!! I'm living in HELLLLL!!!!!!
