Me and ex split up roughly 2.5 years ago. We have managed to maintain a good relationship, friendly and caring since we split up. There have been a few instances were exP has blown his lid over something, has a go for a day, ignores me for a few more and then goes back to his normal self. There have properly been 4 or 5 instances of this over the time we have been separated. That was just for info.
I moved 12 months ago and my next door neighbour happens to be an old friend of my ex and his wife and their DS.
I've made really good friends with my next door neighbour, lets call her Sally. Her husband is also really lovely (lets call him Dave) but my friendship is primarily with Sally.
Last weekend Sally text and said she had come back early from a wedding reception and did I fancy a drink next door. I said yes. She then text and said that Dave had called and invited us to join him at his sister's house where an afternoon bbq was still lively. I said yes sure.
I got there and a few friends of exP (people I had met whilst with exP) were at the party and we ended up chatting. No problem.
ExP dropped our DS off this evening and we were chatting about things, as we usually did. I mentioned the party, mainly due to one of the people setting a petrol can on fire accidently and the party being divided into people flapping and people laughing.
Anyway, he blew his lid. Yelled that it was put of order I was socialising with his friends. I reiterated I was invited to a party by my neighbours, it had nothing to do with the people who were there and the fact they knew my ex. He carried on getting worked up and even insinuated that I had slept with/been seeing one of his friends! I was 
as I haven't seen this person since before I had our DS, who is now 3. This party was the first time I had seen him.
Anyway, several nasty and insulting messages later and I think his tantrum is because he thinks I am going to slag him off to all his friends. Which I have told him I won't do. Coincidentally, I don't think half the people at the party even realised he was my ex as it was never mentioned. I was merely introduced as a friend of my neighbours.
So, I have two AIBUs.
- Was I unreasonable in the first instance of making friends with my neighbour and subsequently attending a party with a lot of his friends.
- AIBU to carry on my friendship and accept any future invites offered to me, regardless if this means mingling with people my ex knows.
I am quite
at the whole situation as I don't see how I have acted badly. I am in no way badmouthing him to people he knows. If anything, I sing his praises as he is a good dad and we have managed a good co-parenting relationship so far.
about this. I'm his childs mother. I'm sure most guys would prefer their ex to have a good relationship with their family so they aren't constantly playing referee.
