brownie

We were married 3 years things were going down hill. Lots of arguing, no trust, husband always out with friends he always made his friends his top priority. I accused him of cheating because of his weird behaviors and the things he would do. I never had any proof but I just had a gut feeling that something wasn't right. I love him with all my heart and when he decided to leave I beg him to stay he said he mad up his mind 1 month he was gone he just came to get few clothes and he kept a the rest of his belongings at my house. We were still seeing each other like Twice a week, we would still be intimate here and there 2nd month he wanted to get off of our lease so he could get his own place so I denied to take him off the lease. 3rd month he was still living with his friend. But 4th month he came and got all his stuff and he doesn't live with that friend anymore now he is living with someone else and he recently whenever I call him his phone goes to voicemail. So maybe he has another phone or something or a new number. I asked his family where he is and they won't even tell me they act like they do t talk to him. I begged him to go to counseling and he refused, I told him I would change he has so many excuses on why he left. He said because we argue too much, and how I don't trust him. But he doesn't give me reasons to trust him. so what do I do help me?? Do I keep fight for my marriage? Or just let it go?
