He admitted the other day he felt down and cried about not being happy with his career and living situation and partly because he felt sad about the loss of his relationship.

Things between them ended on a very sour note, she cheated, broke his heart, the whole 9 yards.

He claims he loves me and is happier than he's ever been so if I really do make him as happy as he claims, shouldn't he be focusing on what he has now rather than what he lost?

We got into an argument about this and he said I can't expect him to grieve exactly how I want him to and that he misses the friend he had in her more than anything.

At the time I had also come out of a 5 year relationship but so much happier now. Can't imagine crying about my ex now.

Not sure what to do here.

Summarize the given text in a few sentences.
<bot>: He admitted to sometimes mourning the loss of his relationship with his ex of 7 years. We've been together almost 2 years, kind of feel down that apparently I don't make him happy enough to just forget..
