tl/dr Dated for a year and half with zero issues, fights, or arguments. Then broke up with me over facebook messenger with a single message.
I M(34) have been dating a F(37) for a little over a year and a half now and last Friday she sent me a single facebook message breaking up with me. Some background is we went to the same school most our lives tho she was a few grades ahead of me. Well we matched on Hinge a year and a half ago and starting dating. She has 3 kids, I have 0 and her 2 sons have the same dad (also went to our school) he was abusive and quite frankly a POS but obviously he's still in the picture with custody stuff. Either way everything had been fantastic, we never argued or fought once! Went on trips/ mini vacations while the boys were at their dad's. Talked about doing stuff in the future, but she never introduced me to her kids because she didnt want their dad to find out. (He's borderline psychotic) She had met most of my immediate family, and never introduced me to any of hers.. (red flag). Regardless we talked every day and seen eachother every other weekend until a month ago. I took her on a trip for her birthday weekend and had a bunch of activities planned, nice hotel, nice dinners, we had an excellent time. Then we came home and I noticed she became a bit more distant.. and last week even more distant. Right up until she sent me a single facebook message saying im an amazing person and she wishes we would have dated years earlier and its not my fault but she needs time to figure out her feelings and she has too much going on and too much on her mind to give me the attention I need. (I was fine with any attention tho sometimes id get upset when we had to miss a weekend but I never showed that I was upset) she said at this point she could offer me friendship. That was pretty much it.. I felt something was building this last month but I didnt think she would end things. Im at a complete and total loss. Heartbroken and not sure what to do. I obviously questioned her sudden decision but ended up just sending a short, sweet message respecting her decision but left the door open should she decide to try things again. Do I give her space, or try to fight for our relationship?
