<human>: So after 6 years of being single and a couple girls who didn't want a relationship, I've found myself in a relationship once more. The only problem is that I'm unsure of how to go about being in one. 

How much hanging out is too much? Am I being overbearing for wanting to see her often? I don't know! Two of my best friends passed away last year, and my other moved out of state, so I've felt kind of alone. Its nice to have someone that I don't feel alone with, but I don't want to take things too fast, ya know?

It seems like its going well, I really enjoy spending time with her and hanging out with her friends, and they all seem to like me quite a bit, but there's a part of me that can't help but think that its all just a passing fancy. I've been trying to just ignore those thoughts and enjoy the ride with the hopes that those intrusive thoughts go away eventually.

I figure the best way to go about it is to just be myself and not worry because if she didn't want this she wouldn't be in a relationship with me. I just want to change that part of me that worries all the time.

Summarize the given text in a few sentences.
<bot>: I tend to overthink things and doubt myself, and I'm worried that I'll mess things up. Any suggestions?
