So I recently went through a breakup in august of 2017, and then started talking to another guy at the end of october, and dating him "officially" in the beginning of december, which was when we first slept together (literally and sexually). I really liked him and he even met my mom and everything, even though we agreed on a somewhat casual/not serious relationship.
I had to go back home for winter break so I did not see him for a month, leading me to overthink all our texts and just generally make myself feel very worthless and depressed, not because of anything he did, but I think because I had too much free time and we had a few serious discussions over the phone/text which made me feel distant from him.
Anyway, I got back a few days ago and I have seen him a few times, but it feels harder to get along for some reason. I feel like I have to put on an act when I know I don't, and I really don't like how I am psyching myself out before this relationship can really begin. Does anyone have any tips on how to relax and just go with the flow of a new relationship and not let your insecurities and past relationships affect your current ones in a negative way?
