Been through alot

So the past year of mine and my husbands relationship has been far from great and I honestly don't know where to go from here.

The first 2 years have been pretty good we got together then we started trying for a baby had a misscarrage then got pregnant again and had our beautiful baby girl and got married there were no signs of any of this past years events.

Now coming to the third year of our relationship just before we moved away from all my friends and family we started to fight a little more and he was becoming a little bit aggressive with me he grabbed my arm and swung me onto the bed and I ended up having finger bruises on my arm, then another time I was about to go for a walk with my friend she was behind my husband when he was hugging me so it looked like a nice thing to do when in fact he grabbed my spine really hard because he thought I was going somewhere I shouldn't be.

Then I stupidly went with him to a different state where I didn't know anyone I was miserable being there and honestly wasn't the greatest to be around because I was always upset he then proceeded to go on tinder for three months without me finding out then started talking to this girl on snapchat and hiding it from me I then found out a few weeks after they had been talking that night I took his phone from under his pillow because I noticed he was being really secretive about his phone and found out and as soon as I did I woke him up and asked him who this girl was he got so angry he was throwing me to the ground trying to get his phone off me. I left the next day and took my daughter that's when I found out about tinder. His excuse was I was making sure you weren't on there, which doesn't seem believable because of this other girl. Anyways I came back believing he wouldn't do it again.

Two months later he was on it again but I didn't find out until 3 months later when he was on it again because he had blocked someone that I didn't know on Facebook and obviously I stalked her on my Facebook and found she was from around where we were living and I messaged her and she sent me screenshots of his tinder and there messages (which weren't flirty but still it's bad enough for him to be on there let alone talk to someone) then there comes the day that he finished work and turned his phone off and didn't come home for two hours. And the suspension of him being closer that he was letting on with one of the people he worked with. I confronted him about tinder and his excuse was that he didn't feel good enough so he went on there, the lack of coming home was apparently due to him having a bad day and felt so shit he wanted to kill himself so he was sitting in the car for that long taking a breather. And the person at work I'm just being paranoid about and that she is apparently an ugly fat midget why would I? And honestly I don't know weather to believe him and just get over it or if it all was actually something to be concerned about?

In the midst of all this I was pregnant with our second child so we moved back down to the area I used to live in he quit his job up there because at 20 weeks we found out there was something wrong with him and needed to see specialists down here and he finally agreed to move back down and hopefully start fresh with me but at 28 weeks we just had him stillborn. Now I don't know where to go from here, I don't know if I still want to make this work or not because I don't know how to put the past behind me and move on but at the same time he moved back down here and is trying to make it work finally, he hasn't layed a hand on me since then and I don't think he has done anything since I last found out about all this stuff but I can't help but wonder if he will actually change or if eventually he will be the same.

So I guess my question is has anyone been in a situation where they questioned alot and never got the full truth but continued to stay and there partner has changed? Or what would you do in my situation?
