Bf is a cheater and liar. Trying to get him out my apt

I am in my 30’s and he is in his 40’s. We have seeing each other since 2017-2018 and didn’t make anything official until I graduated grad school in 2019. Just moved into together in august 2021 (his name is not on the lease). I work a full time and part time to cover pay bills, student loans and etc. still I make time to watch a movie, make dinner and do things with him during my time off or working short shift. I have him pay for half of rent because he has to pay for child support for three children. I cover everything else (water, internet/cable, and etc.). Lately, he has been deattached and sleeping on the couch and plus haven’t had any physical interaction or intimacy in 3-6 months. He mentioned an older friend prior getting together and insisted he if wanted to be with them. He stated no. However, I recently peeped his phone he watch shit ton of porn, smoking weed alot more and he been calling the older friend. She even left a VM on his phone he didn’t listen about she was waiting for him to come over to give him “some”. Tried to talk to him at Christmas about he is unhappy and I think your seeing someone else. He stated no. Trying explain this to man to leave. How do I get him out without cops involved?

If he’s not willing to leave on his own then you’ll have to evict him, most states if they receive mail for more than 30 days at your house you must go through a court eviction process.

I been making him discomforted at the house for him to leave, but he is there after work. I would figure he gets the hint. I don’t know he won’t go to his BMs house to stay or with the other woman. I will be doing letter shortly

Have you just straight out asked him to leave? Or are you hoping he will catch a hint and leave on his own without having to have the conversation?

Hoping he catches the hint. I tried to have a convo with a week or so ago about us and the through a child like tantrum. I put me off him whining
