Ok this could get long but don't want to drip feed.
My child's dad and I have been split up for 7 years, (we were only together 5 so friends longer than a couple) he moved many miles away. We have stayed friends throughout that time even when we have been in other relationships. We would call each other for a catch up a couple of times a week, offer advice, help each other out. I still had his older child stay at my house and maintained a relationship with them too.
When I met my DP 2 years ago he said he wasn't comfortable with my friendship with ex and I took that onboard and reduced contact a lot. We are still friendly but don't talk regularly outside of arranging contact or talking about our child.
Last week I was having car troubles, tried to ring my DP three times but no answer, tried to ring my brother but no answer. Time was getting on and I had to get to school pick up, I knew Ex would know how to solve the issue so I rang him. He gave me the advice I needed in a twenty second phone call and i went and did pick up.
My DP has kicked off massively that I rang my ex, he has said its inappropriate, I need to let go and accept he's not my boyfriend any more and leave him alone. He's saying its a deal breaker, I am so disrespectful, I can't help myself around men, he's absolutely adamant that I knew he would be upset about it so I shouldn't have rang him. He said instead I should have gone back into work and asked someone to help me. It was past 5 so most people had already left and I didn't want to approach a stranger from another floor.
Ex didn't mind me asking him. It was literally a twenty second phone call, it was a very simple problem but as I am a fairly new driver I hadn't experienced it before.
So my AIBU - was I unreasonable to as my ex for advice on my car.
