Has he pushed or otherwise physically hurt you on other occassions?
Does he shout at you a lot?
Is your relationship otherwise happy apart from this incident/issue with his friends?
The fact that he pushed you over is absolutely wrong, it's abusive. Bad enough if a one off but more likely a part of a pattern of behaviour. More worrying still that instead of being mortified by his actions and very sorry he pushed the blame back onto you, told you his friends blamed you too. Gaslighting I think, normalising his own behaviour and telling you that you were in the wrong, and that other people think so too, making you feel guilty and ashamed instead of him.
If it's a simple as a row that got out of hand, he behaved badly and then his friends turned against you then a good husband would say to his friends 'it's a shame you feel that way, I was the one in the wrong, I love my wife and if you no longer want to spend time with her then unfortunately that will mean we can't spend as much time together either'. If your h's friend is calling you he should stand up for you. I would not want to spend time with people who made their dislike of my partner so clear.
I wouldn't be surprised if his friends never said anything of the sort, he just made it up to make you feel worse and put you down. But even if they did say it, they're not the issue,my our husbands lack of support and respect for you, plus his aggressive behaviour is.
