Hey there, I need your help guys.
Background: GF of 1.5 months she's great, very affectionate caring good sex etc. So relationship is all good. Up to last night when I don't know what the fuck happened.
She said she wants to tell me something because we should be always honest to each other and such. So I ask what is it. She then tells me that she has met her ex boyfriend today. I said fine so what does it have to do with me ? She says nothing. Then she showed me their texting on her phone.
I started reading it but then I thought "Wait a second why am I even reading this?"
I then stopped reading and told her that I don't see the reason why did she have to show me this and tell me all about it. If there is no issue then why telling me ? She said that she just wanted to be open and honest and said she's sorry if she hurt my feelings.
Now I know she's done nothing wrong with this but I can't help but feel a bit shitty about this whole thing.
I don't know if it's normal to feel a bit jealous, but I feel like that anyway. The ex was with her for 4 years and they broke up 2 years ago.
I told her I trust her and I've got nothing against her talking to other people including the ex, but just leave me out of it.
Then we had great sex and she kept re-assuring me that she's with me now and there is no problem
Did you think I over react by telling her that hearing about her ex bothers me ? What should I do ? Soft next ? I don't think it'll help too much here as she didn't act disrespectfully.
I think it's down to me to sort this out with myself. I have inner game issues especially when it comes to exes because my previous relationship was finished due to an ex. Right now I can't help but feel threatened by this guy. Do you guys think I'm overthinking it ? I think I won't see her until I sorted this out myself because I don't want this to show too much, that way I'm just giving the ex too much power.
I'm happy to hear other peoples opinion. Thanks

Do you know why she met her ex?

They live in the same town and accidentally bumped into each other. She said they don't see each other often but when they meet they say hi and are just being friendly and polite to each other.
She's apologized many times for bringing it up since this happened and told me that. Also in text today as well. I'm cool with the situation now, it caught me off guard when she brought it up last night I'm not gonna lie, which I've told her. I won't mention the topic again though unless she brings it up, in which case if there is a problem she's done.

If she keeps apologizing for it, that clearly is going to make it harder for you to contain jealousy.

If nothing wrong happened, she has nothing to be sorry about. Tell her the more she apologizes about it the harder it is for you to not worry about. Tell her straight up, if she didn't say or do anything inappropriate that you appreciate her being open and honest, that's why she's a great girl, and tell her you both can consider it a non issue that is in the past.

If she was together with him for that long, it's possible that seeing him/talking to him brought up some feelings. This shouldn't make you jealous. Just be the great, studly guy that you are and that will remind her why she's with you, and reassure her that breaking up with the ex is what allowed her to snag you. If anything, she probably just feels horrible for the feelings that she felt when seeing him or talking to him. That's natural. If you're with someone for 4 years, and at some point loved them, it's normal to be reminded of those times and have feelings come back. But after 2 years, chances are good that if you do as I recommend she'll acknowledge her feelings and put them away again and that will be the end of it.

FYI, any woman who feels guilty about talking to or bumping into an ex so much that she tells you about it, apologizes, etc sounds like a damn good woman to me. One who will adore a guy who doesn't get overly jealous or be a dickhead about it. Don't act like you don't care, just act like a grown up.

Thanks for the tip mate I told her that I appreciate her honesty and that I'm cool with this. Which I am, don't know why did I react so childish. Anyway something to work on the future

You could have handled it a lot worse than you did. I wouldn't worry.

Not to be devil's advocate, everything seems fine. But she is texting her ex also? Seems like the only red flag. Her past should be her past and she should not be talking to an ex if she is with you. Bumping in to him and telling you is admirable, but if she is continuing to talk to him then watch out for complications ahead. Hopefully the contact has stopped
