<human>: Can you succinctly summarize the text in 1-3 sentences?

28/f here, he is 27. Together for about 8 months. 

He started to change recently; less affectionate, mean, overreacting to a lot. I could tell something was up, even though he wouldn't go into specifics.

He told me a couple days ago that he isn't in love with me anymore, and he doesn't know why. He says there isn't anyone else. He still finds me very attractive. He assures me that I haven't done anything. I am a very good girlfriend, even he admits this. I am supportive, and loving. I treat him to dates, and buy him little surprises. I listen to him vent. We have (well, had) fun doing anything. We also have a ridiculous amount of things in common. We have awesome sex, although there is a bit of restraint on his part in the oral department. So what gives? 

We have both had a lot of stress recently (both started new jobs, moving scare, car troubles, financial problems, family drama), and it has put some strain on us. But not to the point that it should break us up.

After talking, and crying, it out with each other, he decided he still wants to be with me, to start over and try and get the love back. He says he can see himself spending the rest of his life with me; that that is what he wants. He has been very sweet, too. But now, the lack of "I love you"s is killing me, because I love him and he means so much to me. My feelings and pride are hurt from this, to the point where I'm starting to lose feelings. What a cluster fuck. I feel like I'm trapped in a bad movie.

Has anyone had this happen to them? I don't know what to do. Do I wait and see if he falls in love again? Do I leave him?
<bot>: my boyfriend doesn't know why he isn't in love with me anymore, but still wants to try. Not sure what to do, so I need help.
