<human>: I've been going out with my boyfriend for 8 months now.  We are in college together, and spent the first 4 months at school, and then 4 months in the summer - most of which was spent apart, with 2 long vacations together.  It's been really good so far, apart from some small bumps of feeling insecure about his feelings for me at the beginning as I was much more affectionate than he is, and over the summer I felt like the relationship was surprisingly great.  

Now we have been back at school together for about 2 weeks, and it's been a little weird adjusting to a schedule after spending all our time/none of our time together (and not having any options), but the main problem that has risen up for me is jealousy of other couples.  I enjoy our relationship and spending time with him, and we have a lot of both meaningful and fun experiences/conversations.  However, I can't help but compare myself to my friends' relationships, which are generally more affectionate and romantic than mine is.  It's mostly stuff that I wouldn't/didn't really care about (e.g. giving flowers), but it's also made me think about how I tend to be more affectionate than he is and am more likely to go out of my way to "show" him I care about him (gifts, organising things to do, etc.). I also appreciate, though, that people have different ways of showing and receiving love.

So, part of me thinks that maybe this is something I should talk to him about, because it is something that is genuinely upsetting me.  On the other hand, I think that the fact that my jealousy only really started when we got back to school might be a sign that I should be the one to work on this, rather than him.  

So what I would really appreciate is thoughts on how I should approach this, and also DEFINITELY some advice on how to deal with being jealous of other couples?
