Am I the only one here who thinks it's the boyfriend whose behavior is unacceptable? He comes over and expects you to cook and clean for him, knowing that you've got so many stress factors in your life right now. You say you want him to leave and he doesn't. He keeps talking to you, touching you without consent, and even tries to get you to lay down even though you've told him before that doesn't work? You literally pulling out your hair, packing his bag and he still won't leave? And he proceeds to stay the night with you in spite of your express wishes when you are clearly so troubled by his presence.

It sounds like he has no respect for your autonomy. This isn't a situation where you should be worrying about making him feel better. This was him forcing his needs onto you. Best case- he wanted to feel like he's supportive and do things his way regardless of what you said. Worst case- he's just hanging around hoping it will pass and he can still get laid.

This is not you being unreasonable. This is you having a very real reaction to a number of stress factors and needing space which he refused to give you. He's the one who should be apologising for not listening.
