<human>: Background:

I'm a 30 (M) who has been split with my ex-wife (30) for over 2 years (married for 6, together for 8 and friends for years before). We have a child together (3yo). Our split was quite messy and we're finally at a point where this is no more hostility or anger. We were great friends before we hooked up in our early 20s and while neither of us want to be with each other romantically, I think we both miss the friendship we once had. We still chat a fair bit when swapping over our child etc and we've bumped into each other a few times while out at pubs/mutual friends parties and it's been mostly good.

The problem lies with my current GF (28F). We have been together just over a year and she does not really want me having anything to do with my ex from a social point of view. I guess it is just her insecurity but it's starting to make me question our relationship. EG. the other night my EX was wanting to head out for a beer and invited me along. I had our child for the night but could have arranged an easy sitter to go and have a beer with her. I mentioned this to my GF and of course she told me not to, and got upset, so I didn't go.

I understand I have to be sensitive to her needs as she's my partner now, but it really pissed me off. Part of the reason I hated being married was not being able to do what I wanted when I wanted, yet here I am again! I really want to stay friends with my ex-wife, and while I can do so without hanging out socially I actually do want to hang out with her sometimes. She's still a cool person, and I have no interest in doing anything with her (pretty sure she also has a casual BF).

Am I just being a selfish insensitive twit or what?

Condense the text into a few key points
<bot>: I want to be friends with my EX-Wife but my current GF doesn't see what I would want to and has made it clear that I essentially can't be. Just looking for advice.
