<human>: So I've recently been seeing a guy as of late. Its the first time I've really dated in probably two years, and so far I'm loving it. We have so much in common, we never run out of things to talk about and I love his personality. But there's something that keeps bothering me.

I always feel shallow talking about it but he used to be skinny, like 140 pounds. He's not anymore mainly due to a big onslaught of events that happened after his last breakup a few years ago that caused him to start eating a lot to cope with his feelings. He's shown me what he looks like when he was skinny and stuff, and sometimes I wish I had the skinny version of him and it bothers me. I shouldn't be thinking that, its so shallow and sad and I like his personality but we're having a bit of trouble clicking physically and I'm scared to get any further with him because I'm worried that I won't enjoy doing anything else because of I'm having trouble liking his body. I always hate thinking about it cause I feel shallow and selfish whenever it crosses my mind, but I don't know if that's the issue or something else is.

We tend to hang out a lot, and he overwhelms with how affectionate and stuff he is, and we're figuring that out but whenever I bring up the insecurities about how he used to be skinny to anyone else they usually shut me down and tell me to give him a chance, and I definitely am, and we're starting to get more physical and a little more serious now but this problem keeps popping back up.  He's trying to lose the weight again because he's self-conscious about it, and he says that I'm a motivation to do it, but sometimes it feels like I'm subconsciously telling him to lose it.

Can you summarize the given text in a few sentences?
<bot>: Seeing guy who used to be skinny and I thinking about when he used to be skinny and not how he is right now
