I have been dating the most wonderful guy for the past 2 months. Everything is going super well. He hasn't given me any reason to doubt him, and has been very honest and open.
There is only one thing that is making me pause and I would love to just get another perspective. He dated his last girlfriend for 7 years, and they broke up about 5 years ago. She went on to date someone else soon after (like a week after lol), got married and now has kids. They shared a dog, but that dog now lives with her - which my boyfriend occasionally pet sits.
The thing is, he still mentions her quite a bit - every other conversation, people he meets - she always comes up. Like "my ex was this", "my ex had that", "oh no worries, she is married with kids" etc. Even when he met my friends for the first time, she came up. I now also found out that they share a spotify account. Last night she texted him asking if he wants to adopt a random dog from another city (his dog recently died) - I found this to not only be a bit insensitive (too soon after his last dog), but also... why are you interfering in your ex's life like that? I want to build a new life with him, and it feels like she is just there mingling.
I do trust him, and I don't think they would ever get back together or anything - but it just makes me think why his mind defaults to her so much. I ended a relationship last year, and even thought it's much more recent - I legit don't think of my ex or bother mentioning him.
Now, I don't mind at all someone being in touch with an ex, especially when a dog is involved. And he says it's all just cordial. I think he is just a friendly no-drama guy. It's just something that rings a bell, and would love to hear other people's opinion.
