Guys, How can I boost my man's confidence when he tells you you aren't doing enough to help?

My man has become very insecure and has accused me of cheating several times. I have told him to go through my phone leave my phone open around I let him see everything on my phone minus when I'm getting presents for him or something special. He tells me pretty much that no matter what I say he will not believe me. He has accused me of cheating for over a year now. It has gotten worst since his mom started saying I was sleeping with other guys and our baby isn't his. We have been together for almost 5 years and never stepped out. The only thing that has really changed is we have a 17 month old that has taken time away from us
