So I met this guy a couple of years ago while studying abroad and we became good friends. We would sleep together once in awhile but aside from that we were pretty normal friends. Almost a year after we met he started dating someone seriously and I would barely hear from him when it started and then months went by without us seeing each other or even talking. After they broke up we started hooking up again but it felt different and weird. It stopped when he basically stood me up and just ignored it. After about a week he messaged me asking what i thought his type was (idek why he asked) and we haven’t spoken a word to each other since that convo. Which was a couple of months ago, and now he’s seeing someone else. But it still hurts. I don’t even know what to do anymore. I’m tired of being sad every time i find out he took someone out on a date. How can I stop liking him?
