<human>: My boyfriend and I have been since the last year of college (UK), and we have managed to keep up a long distance relationship during term time for two years while being at different universities. 

We try to see each other every 2-3 weekends. During these weekends, we are excited to see each other, we kiss and cuddle and have sex, but the next day everything feels a bit awkward and strained. 

I feel like he's under my feet/I'm under his, and we have silly snappy arguments that make me feel like crap. They  usually embarrass me because they're in front of other people, and he tends to initiate it. It's all resolved by bedtime though, and we have a fantastic sex life (we lost out virginities to each other, and know exactly how the other likes it), but lately I think that's the only reason I'm looking forward to seeing him at all.

I am inclined to think it's just that we don't know how to act around each other because we only spend the odd weekend together, but it's a similar story when we're home for holidays too. I spend quite a lot of time around his house, mainly because all our friends live closer to him than me. This means we spend most of our time around other friends too, which dilutes any problems we may be having.

I've been having these feelings for about 6 months now. There are lots of reasons I haven't just broken up with him. I still love him, but I feel like we've run out of things in common and are just going through the motions until we can get each other to bed. I am feeling held back by the relationship now, and almost like we've outgrown each other. I'm scared that if I break up with him, all my friends will turn against me, because we have a lot of mutual friends, and outwardly we seem happy together.

Can you condense the text into three sentences or less?
<bot>: I feel like I've outgrown my boyfriend from 'home' into my third year of university, and the only thing keeping us together is physical
