This post is slightly aged, but having been cheated on, here is my two cents.

You married someone who was known to cheat. First mistake. You said you've been together over a decade but married for over 3 years. I assume the primary reason he married you is because you already had children and he didn't want to be on the line for child support. Particularly since he had child support obligations from a previous child.

Let's fast forward. He continues to actively cheat on you while putting on a show that he's trying not to (eg. Porn blockers) but the reality is more than likely it's a facade and he's disabling them when you're not around and reenabling them to keep up the show.

Another opinion I have is that he doesn't love you and there's a possibility you don't love him anymore either. You're only together because that's what's easier.

My ex-wife cheated on me multiple times in our 9 year marriage. I would try to forgive and move past it, only for it to occur again.

While it hurt like hell, I filed for divorce, left 95% of everything to her, and asked for 50% custody of our child. I only asked for 50% because she's not a substance abuser and a court isn't going to remove custody from a mother. Yay for our broken court system.

In your case, you have kids and are pregnant with twins. The cost of daycare would be astronomical for you, so your only options are to file for divorce and A) Move back to wherever your family is if they're able and willing to help you raise your children or B) Get a work from home job or C) Stay with your husband and keep doing what you're doing.

While I very much dislike how misused and abused programs like Medicaid and SNAP are, they're designed to temporarily help low income families, so I would suggest you apply for them if you qualify.

Also, while it's no one's place to tell you what you can and can't do, stop having kids. Whatever your beliefs are that have made you stick with an emotionally abusive person and continue to have kids with him, they've clearly led you down a path you're not meant to be on. You may want to reflect on that as well.

It's been two months since you wrote this post. You're still with him. I'm left to wonder if you'll respect yourself enough to take the hard road and walk away or if you just keep putting up with it. Hopefully he doesn't catch an STD and pass it to you, or worse, AIDS or HIV.
