<human>: He got out a really long-term relationship with arguably the love of his life. Her family was the primary problem and he had too many disagreements with them, though they were having issues between themselves even long before the final breakup. From what he told me, it was mutual and obviously sad but for the best. When we met he was very honest about everything and it didn't sound like there were any lingering feelings coming from him. I asked him about it before because I was doubtful but he assured me that he didn't have any more feelings left for her. 

We start going out on dates, talk everyday, have a lot of fun together and everything's great. A month in was when I asked him if he was over his ex and we had an open discussion about relationships. He told me he wasn't ready for a relationship and wanted to wait until he was sure but he was ready to date me. He also mentioned how him and his ex were friends for a while before they dated, and it made it sound like he wanted to be friends for a while before officially dating? The thing is, his previous relationship and ours is completely different because we didn't start out as friends - we got to know each other through dates and we were interested in each other romantically. I don't know why he's comparing it the same.

Anyway, the more he opened up to me, the more I realized that he would've probably married this girl if her parents weren't such a problem. I don't personally know her so I can't speak much of her as a person, but I am intimidated at the kind of relationship he had before he met me. It ended for a reason, but I've also never been in a serious relationship before so I'm not sure how to do it. How do I move past that?
