The Effects of Being Cheated on

My SO and I have been together for 3 years. For 18 months of that time, he was incarcerated. I supported him through that time. He just came home in December. He was only home for a month before he went out to a bar and cheated on me. He kissed another woman and was telling her he was single.

We took a break, b/c he asked for one. During that break he used dating apps like Tinder and OkCupid. When we got back together he was still using those apps for like a month before I found out, which I couldnt understand.

Then in February I found out I was pregnant. A month goes by and he sneaks away with his friend to go out to a bar. I actually drove there to find him. I found his friend, but he was no where to be found so I knew he was up to no good.

he ended up being with this girl, making out and dancing with her all night. Saying he didnt have a gf. I even saw a video of it the next day. I took him back because Im pregnant and love him and want to be a family.

at this point Ive become the gf thats skeptical of her bf going out. My trust has been demolished. I kind of tightened the leash. I normally go with him when he goes out.

The times I havent hes gotten girls #s. And its a slap in the face b/c its like he doesnt realize how much being cheated on has hurt me. Now he always complains he feels trapped and cant have a life. I just want to trust him and he wont have to feel that way. How do I find middle ground where I can feel secure and he wont feel trapped?
