<human>: Can you give me the gist of the text in a nutshell?

So things seemed to be going really well when we were just seeing each other and when we started dating but lately things just seem off for me. Bear in mind that she hasn't mentioned anything like that too me so this could just be me getting into my head. The main issue is that I feel like I am experiencing low self esteem right now and it's crippling my relationship with my girlfriend and will only continue to make things worse. I have this thought that if I'm not keeping her constantly entertained when I'm with her, texting her or talking with her than she is losing interest in me. This is affecting my confidence the more I think about it. I feel like the relationship will start becoming only sexual and eventually when that gets tiring it'll just end...and that's not what I want.

The more I think about this the more I feel like it will lead me to become clingier and just annoying in general which is not the kind of person I am. This could all be because I haven't been in a relationship for a long time so I might just be overthinking and trying too hard to repair something that isn't broken.

Just looking for some input or advice on how to change my thought process.
