So I have extremely lovely boyfriend - whom I am deeply in love with and he is with me (or so he says). Its quite early doors (6 months) but we have been spending lots of time together and very quickly into each other iykwim. He basically lives at my place of late. Im making that point because in the past 8 years of dating I have never gotten this close this quickly and its extremely lovely. I believed he was the one tbh after quite the time looking (Im 51 - past shitbox of a marriage).
Anyway, his previous girlfriend who he told me all about. He was in love with her , but she cheated on him with her childs father, he dumped her (but took some time to get over her), and they remained in touch as 'friends' (that part I don't get cos they didn't see each other just chatted a bit on text I think), and he said she spent about a year trying to get him back. He always said he wasnt interested, and she is with someone else. She was due to get married now.
This was all I really knew and I wasn't interested cos not my business. I did think it was odd they were facebook friends but he said they barely talk so I just didn't worry, cos we spend all our time together and its all good. HOWEVER, this weekend he started telling me how she is single, the wedding didnt happen she has been posting about how devo she is, how she has been treated so badly. I asked a bit more and he showed me that she had messaged him an old lovely dovey picture of them together in June with a 'how sad' and a sad emoji. Theres been no contact since - or so it seems - but they are still friends of facebook.
It made me feel very very insecure, threatened and panicky. I went quiet, and he reacted really lovingly telling me how sorry I was, how much he loved me, he wasn't interested in her - yada yada, and that he would unfriend. I said a woman you were once in love with, and pursued you for a year, sent you a very obvious 'i want you back' message just 2 months ago and is now newly single!!!! And we were together then. I asked how he would feel if it were him, he said he would hate it. I said I would never tell someone what to do, but I do not want to EVER feel insecure and jealous again - its a hideous awful emotion and I don't deserve to feel it. I said I didn't want to talk about it anymore, and he can do with that information what he wants. Obviously I wanted him to have unfriended and blocked her but I have checked today and they are still friends on there.
I just feel the whole thing is immature and just not something I want any part of. Im 51 ffs and Im checking someones facebook friends, its just not me, I hate it. Its put me right off tbh. I don't want to feel this teen angst knot in my stomach. Up until now, it felt like such a healthy, secure love. So different from my marriage which was awful. This has been exactly what I wanted and needed. But I just feel there is this woman out there, newly single and heartbroken, who is now going to go hellbent on pursuing my fella. And worse - he is just still facebook friends with her - and they aren't even bloody friends! I find that baffling and disrespectful. It makes me feel maybe he enjoys the attention from her? He is getting something out of it surely, because he doesn't want to be with her (allegedly). I dunno my gut is saying he wants her chasing. I really don't want a bar of this dynamic though. Apart from this, he makes me incredibly happy and I haven't felt this way in years!
So am I just completely overreacting, being a jealous knob and worrying about nothing and ruining something completely fabulous because Ive been fucked over in the past? Or is this something to worry about?
TIA
