BIL keeps making rude comments

Hi all! Just wanted to post to get some feedback as navigating in laws can be tricky! My fiancee and his sister have a close relationship, and she’s of course married. The BIL makes it clear that he cannot stand my fiancé, and to me, seems to go out of his way to be rude. First off- the sister and BIL got married a few years ago, and the BIL didn’t even invite my fiancee to his bachelor party…but here’s the kicker, all of my fiances friends are the BIL friends now and he invited all my fiances friends but not him. MARRYING HIS SISTER at that. Anyways, nothing was said about that, but fast forward to another family event. A death in the family and we go out to eat afterword, no drinks have been consumed (I should mention the BIL constantly drinks and makes stupid comments then) and we are talking about my haircut and how much I paid. I mentioned to the how much I tipped my stylist, and his response was “geez, no wonder you live where you live”. Mind you, they live in a SMALLER place than we do. He’s also constantly making comments out loud about my fiancé, for example my fiance called him to show him something and the BIL says “I guess I’ll go, I’m a glutton for punishment”. When he was called oh about his mouth, all I got is a 1 sentence apology from Snapchat. We are both 30+ by the way. My man and I are now in transition and got a nice new place, the BIL asked how much we pay and we said and he said “oh no, I could never justify paying that”. Okay?? Cool! So we get the place and they come over for a tour, our mutual friend recently moved and have a place like ours, after the tour his BIL says, “nice place, but it’s smaller than (said friends) place.” Also, not even important because who cares about gifts, but every Christmas we get him something and ever year, he gets us nothing. Idc about material things, I think it just says a lot. He supposedly “isn’t good at getting people gifts” but who is? He also blames everything he says or does on him being drunk, which to me is a cheap cop out. Am I over reacting, or is this blatant small jabs at us??? Because I am nothing but nice and supportive with my in laws and it’s like they just can’t stop with the comments. Maybe I’m just sensitive? lol
