It ended up in a fight!
Basically the short version is my BIL FIL2B is a bully, he bullies his wife (and has been known to use his fists☹️) and his 3 children. So he naturally thinks that he can bully anyone that his children bring home. Up until last week he was fine with BIL, but then his attitude towards him totally changed and he's been trying to bully him all week.
It all came to a head on Saturday night when the boys were out having the stag night. THe FIL2b chose to bring his 14 year old son (including buying him pints until he was legless) and told everyone there that he's his son and there is nothing anyone can do?. My H and his dad are members of a men only social club and BIL wanted to go there as the drink is cheap and as its all members the atmosphere is good. My H called the club earlier in the week and gained the permission of the committee to allow the rest of the party in, not thinking for one minute that a 14 year old would be brought along. The club is strictly over 18's with no exceptions.
H and some of the others decided to go out a little earlier to watch the Man U match and told BIL about it and he was happy to go, he then called on the day to say he'd changed his mind and would meet them later at the agreed time/place. We now know that his fiancee fobade him from going out early!!!
They all met up later on at the only bar in the town that does not have doormen as it was the only place that the 14 year old could get into. However still at this time my H and the rest of the stag party had no idea said 14 year old was going. BIL did not know that his BIL2b was going either. They assumed that they were all meeting there as it is a well known bar in the centre of town and they would then move round to the social club after everyone arrived.
When it was time to leave my BIL FIL2B said he couldn't go because his son would not get in and the rest of the party then had to decide what to do, they all said the choice of where to go was down to BIL as it was his stag night, he opted to go to the social club as that was the original plan that was made just after Christmas. So off they went leaving his FIL2B and BIL2B in the pub. About 5 minsutes after they arrived at the social club BIL phone started ringing, H saw the name on the screen and it was the fiancee. She was calling telling him to get is butt back round to the pub where her dad was and sit with him and her brother. Apparently she had known that her little brother was going too and did not say anything. So poor BIL went back round to the bar.
As soon as he got in the door of the pub his FIL2B jumped up and started screaming abuse in his face calling him a selfish w@nker etc etc for going off and leaving him. FIL2B continued that he was out of order for doing what he wanted to do on his own stag night etc and then told him that if he even tried to lift his hands to him that he would be on the floor before he knew if, WTF!! Finally he then told BIL that he was ready to have a "rumble" with his dad. The whole bar had descended into silence and 2 of the bar men were standing guard in case punches were thrown!
BIL left the pub and headed back round to his family and friends on arrival my H something was wrong with his bro and pulled him to the side to ask what was wrong, this is when the whole story came out. My H was livid (he's always been very protective of his brother) and went and told his dad. 5 of them (My H, my FIL, H cousin and 2 family friends) then went looking for BIL FIL2B, who had by this time known he was in the wrong and had disappeared!!
Oh dear, tensions are extremley high now and I dread to think what would have happened if my H and the rest of them would've got a hold of the FIL2B. My H probably would've been arrested and FIL2B would be in hospital!!
My PIL and H are now worried about the wedding, as the FIL2B is known for getting a bit aggressive once he's got a drink in him and may kick off again. He did apologise to my BIL the next day, but its since came out that its not the first time he's had a go at BIL then later apologised, but BIL said nothing as he didn't want to cause a fight, so really his apologies mean nothing.
Sorry for the long post, but the atmosphere is horrid and no-one is really sure how to handle the situation, I will as always be staying out of it and I'll be keeping H as far away from the FIL2B on the wedding day, which may prove difficult as my H is best man. My H has said to both me and his parents that he will not fight with the man on the day as he would never ruin the day for his wee brother.
