Extremely Confused

After 2 years of marriage my husband told me that he loved me but not like a husband should and that he wasn't devoted to me like a husband should be, and that he was leaving me, this was in December.

Then he told me that he was concerned about his health and that after he went to the doctor to find out if everything was ok or not, then he would decide if he was coming back or not, because if he was sick he wanted to do all the things he has always wanted to do, and that he wouldn't be a good husband to me.

Then in January, he started texting/calling wanting to spend time with me. Everything seemed to be going great, and then at the end of January he told me that he had a long talk with a friend and that he realized that even though his love for me is not the same as mine is for him, that we still love each other and that he was happy with me so why would he leave. He told me he would be moving back or starting to move back home in about a week.

Valentines Day he gave me a very beautiful gift, and he was suppose to be moving back that following week but then he said it would probably be the following week.

So finally i asked him if he was really planning on coming home because I thought that maybe he was having reservations about coming back and i wanted to make sure he was coming back for the right reasons, and he lashed out at me, told me how i didn't handle any of this very well, and again that he doesn't love me on the same level as i do him, and that i was pressuring him, and that he would rather it be over and done and to be on his own, because all he was gonna do was continue to hurt me, and that he accomplished his plan which was to give me a better life, and that he feels he has done that.

Then he came by the house yesterday to pick something up, never spoke to me, never asked if i needed anything.

I am completely confused, some people I've talked to say they think he's going through a mid life crisis, but i don't know, i don't even fully understand what has happened. I mean our life wasn't perfect but it wasn't horrible, there were definitely more good times then bad, and the way the conversation has gone since December, I am totally confused!

Am I looking at this wrong, am I missing something, because I'm not stupid, but I do not get what has happened or why!
