Would you find it suspicious?

Maybe I’m overthinking it. Or overreacting.

My bf started working with this guy that’s a bit older than him. He’s told me this guy has went out on his wife. My bf talks about him all the time. They text a lot. Lately, my bf has been sleeping with his phone under his pillow so I don’t get it. (I’ve been using his prime account.) His phone is constantly going off since this started.

A couple weeks ago, the guy he works with randomly “gave” $140 to my bf to take us to the zoo. He said it was because he felt bad that my bf broke his promise to us about going. My bf breaks promises all the time.

Then two days later, my bf and I were having sex, which we haven’t done in months, doggy position- and my bf said afterwards that we should have anal because “backyard doggy is the best doggy”

I’ve NEVER done anal with him. I’ve also told him about me being uncomfortable with it due to being messed with when I was a kid. He brought it up again the next time we did it. He also does this weird baby whimpering thing when he tries to get me to have sex with him, it’s cringey.

I also was doing laundry and noticed there was a bit of ejaculate on his underwear in his work clothes. He always goes straight to the shower after work, so I doubt he did that in that time frame in the bathroom. If he did it himself, he would have just done it in the shower. Wouldn’t have gotten on his clothes.

Would you think something is up? Also, his mom is a lesbian, but his dad was homophobic and would have shunned him if he was gay. His dad passed away. But Surely he would tell me if he was bi/gay? If he is, he shouldn’t hide it and be honest with me. I’ve been with a few guys, and my current bf has just been very different when it comes to sex.

*update- he deleted the messages. I heard his phone go off multiple time, and I looked and the messages were already gone. I broke up with him.
