Hi I'm new here and I'm looking to vent a bit.. I hope I came to the right place.

I've been with this guy for almost 5 months. We're very happy together and we trust each other. However, I have this habit of over thinking everything from the slightest thing. Usually it happens with things related to him (since he's always on my mind and I'm always talking to (and about) him but it also happens with friends. For example when he doesn't start chat conversations with me and let's me start them, and he does this more than once I start thinking of all the possibilities. Or like the fact that he does start conversations with a close friend of ours and they talk about personal stuff too (mostly about her). With this same friend though, I worry that maybe sometimes I annoy her from the way she behaves, and sometimes I wonder if being open to her completely is actually a good idea. That is another (bad?) habit I have, of opening up to people. That's how I get close to them. And then I start doubting it later on in the friendship... Doubting if it actually was a good idea. I'm also worried that if I open up to my boyfriend about this, I'll end up annoying him and I don't want that. He's not the jealous type. He trusts me. I do too but somehow I worry about everything and over think everything. I don't know what to do.
