So, DS went on a little holiday with his dad this weekend, so I decided to take myself off to the pub for a couple, someone I took to and picked up from hospital last week wanted to buy me a couple of drinks to say thanks and I never get time to socialise so I was looking forward to letting my hair down a bit. Especially since my DS had been in hospital with a seizure earlier this week (although better in time for his holiday).
DP was working, in the same pub I went to.
I was sat outside because it was busy talking to DPs friend, I said I wasn't out long because I didn't have much money (summer holidays, school uniforms etc) and he started shouting that I did have a lot of money and he knows what he sees... I'm presuming he's talking about the fact that we have just got DSs new motorbility car... Which I would trade back in tomorrow if it meant DS didn't have difficulties... But it let it pass and changed the subject.
Then some other guys came over and were chatting to DPs friend and it got onto fashion as new guy was wearing some styling clothes and new guy said to me "is your coat x make? I don't really like x" (this was in context of the conversation which I don't remember word for word but it wasn't said nastily)
DPs mate then started shouting at new guy telling him he was calling me common etc, really let rip on him. I said I wasn't offended and to leave it but he carried on, so new guy came and sat next to me visibly rattled and started saying he really didn't mean offence, so I changed the subject and we had a conversation.
DP then came out on a break and sat with me and new guy and I introduced him. New guy then asked if we lived together and I said no, our routines are too different for that just now. DPs mate then went off again shouting at me saying that DP does pop round mine and why was I saying that? DP had to go back in at that point but told his mate that we didn't love together and told him to stop being a dick.
Anyway fast forward a bit. New guy had (ran away from the scary man) left and DPs mate called me over to a conversation he was having with a different new guy (new guy 2)
As I walked over the conversation started getting really heated and DPs mate was shouting in this poor guys face, they were arguing about political differences of opinion. DPs mate called this guy a racist and stormed off.
New guy2 then started telling me he wasn't racist and I had a 10 minute conversation with him telling him it was fine, it was none of my business etc. Then I left and went and sat with my friends.
DPs mate then came back over to me and started shouting about how his life was shit and why was I cheating on DP with all these men. I didn't understand what he meant. DP came out and told his mate to stop it and told him that I could talk to who I wanted, and then I just went home.
DP then told me later that his mate had said earlier that he was going to get really drunk and shout at someone today. Seems I got in the way and took the brunt of it.
I just feel like I needed to let my hair down and have a break and that I've just ended up being followed around my someone who wanted drama and who has ruined my only free night this year. 
My first thought is that I never want to talk to this man again. But he is DPs best friend and sometimes our paths cross, when I pick DP up from work and things like that.
So should I just let it drop for the sake of DP and his relationship with his friend, who is actually normally a nice guy. Or should I stick with my gut and never talk to him again because I can't be doing with the drama?
