Am I crazy or is he???

I have not posted for a while. H is back home. We have had good times and bad.We have not spoken about the affair or our relationship since he has been back. I tried to bring it up and he got defensive. He was working on vintage bicycles and doing a good job and I took a genuine interest.We have been working together and going on occassional bike rides together too. He threw himself into the hobby and then all of the sudden said "I don't even care about it any more." He said he is depressed and that he hates everyone and that everyone "settles" in life.I tried to just listen and not take any of it personal but it really felt like he wanted me to. I suggested he might be bipolar he said don't EVER suggest it again. I still think this.He has been very impatient with me and yelling at me a lot and I have not been just taking it like usual. Right after he yells at me he will kiss me or reach out and grab me and show affection. It makes me feel like I am losing it. I don't want him to never tell me how he feels but how do I not take any of it personal. He has been acting like this since he went out with the guys one night which makes me suspicious on top of everything. I don't want to lose him but I really don't feel as if he appreciates all that I am doing and how much I love and care for him. How do I know if/when I should give up?
