I've been dating this girl since mid November, and everything has been going really well since. We had sex for the first time last week and it was great. My feelings for her have been growing and so have my anxiety levels for some reason. I should be feeling happy but I'm not! I don't know why... It's becoming a problem in my everyday life. I don't train as intensely and I've been eating less. When I'm with her, I'm totally relaxed, cool and happy. But when she's away from me, I can't stop thinking about her and I become so paranoid and I over think things. She hasn't given me any signs that she's losing interest. In fact, she reassures me that she's happy by making future plans, texting me all the time and giving me affection.
I know I sound like a p#ssy, but it's getting to me and I want it to stop.
Any thoughts...
