<human>: My boyfriend and I have been together about 6 months or so, and we were friends for 2 years before we started dating. When we first got together, there was that awesome honey-moon phase that everyone usually goes through. After 2 months of dating, I went abroad for 3~ months, and now we're back together. We're semi-long distance, so I usually only see him on the weekends.

Lately I've had some complaints and I don't know if it's our relationship that needs working on, or just me. He's a great boyfriend and is everything that I could ask for, but I find myself getting upset at petty things, even when we are together. 

I feel like we're growing impassive towards each other, don't talk as much, sex and other activities aren't as spontaneous, etc. Also, I get really insecure because for the first part of our relationship he would always comment on other girls looks in front of me (he's since stopped after I brought it up twice), but I do catch him checking out other girls in front of me and that really bothers me. But again this complaint seems so stupid, because everyone checks out other people! 

Because our relationship is really stable and and he always treats me well, I feel like my complaints aren't valid. I also have a hard time talking to him because he tends to bottle up what's bothering him, so when I bring something up he usually shoots back something that's been on his mind instead of helping me work my problem out.

Can you condense the text into three sentences or less?
<bot>: I have an over-all wonderful, healthy relationship, but lately I've been questioning it and can't tell if I'm being ungrateful and should drop it or  bring it up with my boyfriend.
