Grrrrrr

Been with my boyfriend a year. He has REALLY BAD trust issues and paranoia to the point hes accusing me of cheating 24/7 when im genuinely not, baring in mind we live together. He sees my phone , i see his, he keeps telling me one minute he wants me then he doesnt then he does and then he doesnt again says we not working. If i dont want to have sex for just ONE night then it suddenly means im sneaking out again night to have it with someone else. He doesnt let me take my phone into the bathroom he takes it off me and makes me leave it on the side where he can see it.
