I'm 25, I have a 3 yo relationship. Lately a girl texted me and she got sexual pretty fast, she looks hot. She wants to come over this week. But now thinking about it and getting to actually fuck this girl, I feel like in a dark place and I feel like I want to cancel the date. it's not that I'm thinking about my relationship, I don't really care that much, but I still can't find the source of this sad feeling. FYI I've only cheated on my gf only once at the beginning. I'm thinking that I just fell in this comfort zone of only talking to my gf and I get an odd feeling to fuck sb new. Did u guys had the same feeling?
