Am I over reacting

Sooo... my husband was just trying to reset his password to his bank account but he didn’t remember it. He eventually figured it out and remembered that his password was his moms bust and waist size. (His family jokingly had this as their garage code for like a month.). Is it odd that I feel weirded out? Like there’s other numbers hes used for way longer is it not odd he’s using those?

Now listen, if this was just funny and random and they had used those numbers for awhile I’d get it. But also, there’s some other stuff associated with this that just make it that much more uncomfortable for me. First, he squeezes his moms ass... dead ass she’ll shove her butt in his face and he will SQUEEZE it I get they think it’s funny but it feels weird. There was also one time when he was trying on jeans and he came out laughing because they didn’t fit and she made a comment saying “ it’s because you’re packing a huge dick.”. She also gave him money to get more jeans once which we didn’t need the money but it was a sweet gesture, so we went to the store and she texted him the entire time asking for mirror pictures of him with the jeans on to see how they fit. Idk...I feel I’m being ridiculous but I also am so confused because he’s a married man. I understand being super close to your parent, I’m close to mine. but is this not creepy??? (I’m also a victim of incest so maybe that’s making me overthink it???)

To add, I love his mom but there’s some other issues to where she is pretty blatant she’s in competition with me for her sons attention. Everything she does is a way to grab his attention. We don’t even live in the same state but she still smothers us, most recently she’s began using me as a way to talk to him. Ex: hey how’s ****. Why isn’t **** texting me. She’s always in our business and he won’t make decisions without her input. There was one time we were renting an apartment and we’re having issues with the landlord, He called her and told her about it and she immediately said “I’ll call I’ll get it taken care of”...didn’t even ask me to call. She came to our place once and reorganized all of my shelves because she didn’t like them how they were (without asking). She’s also used to show pictures of her in bikinis when she was younger to him and saying “I’m hot aren’t I?! Look at how nice my boobs are, look at my abs! Aren’t I so hot?”. It’s all so difficult because she took me in when I was in high school due to family difficulties and played the role as a second mom to me. She payed for me to have a phone, she payed for my college. I never asked for these things but she always did it anyways so now she uses that against me if I or him don’t respond to her immediately.

To add!: I’ve discussed with him and he says “it’s not like that” or just smirks while I’m talking to him about it. His face gets super red and he does not see an issue whatsoever with it.
