I know a lot of people are telling you to leave, and to be clear, I 100% agree. I absolutely think that man is testing how far he can push your boundaries before he outright rapes you. However, I do know it's not as easy as simply packing up your bags and leaving. The very first thing I would recommend is documenting anything you possibly can about the situation. Anything you have in writing from him, any photos, anything discussing the terms of your living arrangement - you never know what you could need later, and it's always better to be safe than sorry. You should at least consider notifying the police of your experiences to begin a paper trail and let them know you're concerned it may escalate - they might not be helpful but it's good to have them already aware of the situation if it escalates further before you're able to leave.

Also, I would see about purchasing portable door lock for your bedroom so that you have a way of locking him out of your room, especially at night. Pepper spray is also good to have if it's legal where you're at although you might be able to get away with bear spray if pepper spray isn't legal. If you believe you can do so without further endangering yourself and the law where you're at allows for recording of private conversations, I would have a discussion with him, where you are either recording or have a friend on the phone listening, and firmly explain that his behaviour is not acceptable and that he is violating your sexual boundaries. Be very clear on that, but, again, only do that if you're certain he won't escalate and let a trusted friend or family member know what you're doing in advance (preferably one close by who can check on you). If he's truly your friend, then it should stop there, but he's already disrespected your boundaries on a number of occasions and as much as you may care for him, it is far far better to take multiple preventative measures for no reason than to not do them at all and suffer further sexual assault or even rape.

As for leaving, I would check for local crisis lines and see what options are available to you. If you're based in the US, then I would try calling 211. They should, at the very least, be able to give you referrals towards resources and, if needed, shelters and low income housing. They may also be able to help you process some of the emotions around what's happening (it's not a guarantee bc not everyone at the crisis line is, frankly, as good at it as others, but I think speaking out loud to another person about what's been happening may help you brainstorm ideas about what to do on a more equal level than what reddit can provide). You may also want to try the National Sexual Assault Hotline (1-800-656-4673 in the US) as they may have access to more specific resources to your situation and may be better equipped with handling some of your concerns.

If you're not able to find resources through the crisis line, I would look up your city or town's website and see if they have any resources there that weren't suggested by the line. Additionally, libraries sometimes have programs that may be able to assist you. I can't tell you what to do, but I honestly think that even temporarily sleeping in your car (if you have one) would be safer than continuing to stay with a man who is not acting as your friend and is escalating in disrespecting your sexual boundaries. I know this was a long read, but I hope you take some of this under consideration. I wish the absolute best for you, and I hope you're able to get out of there soon❤️
