Over the past few months (since August) I have been dating someone and was starting to really like them. It wasn't getting serious or anything but we were going out and enjoying each other's company. A couple of days ago he told me that in the last month he got back in a relationship with his ex. In the last month I've been with him, eh, intimately and was really into him more than before. Him telling me that crushed me and I feel extremely hurt and betrayed. I'm so angry for being led on over the past few months and especially this last month with him having a girlfriend and me not knowing. I feel stupid and like I should have seen the signs of him being kind of dodgey and weird. I have cut him out of my life but am still so sad. This on top of the increasing severity in depression and suicidal ideation is killing me inside. I'm just hurting really badly and I feel even more lonely than I already did.
s* The thing that makes it worse is just the feeling of betrayal and knowing that someone I placed trust in lied to my face numerous times. Also, I thought I was the only one he was involved with romantically. Oh well, at least it didn't go on for longer.
