Using my husband?

I've been married to my husband for 2 years now, known each other for 5.

Our relationship isn't tinkle pink. He has flirted, cheated and lied to me on numerous occasions but I'm not one to give up when I know he's a good man but he just do bad things. 3 or 4 months ago, I found out my husband who's 25 was having inappropriate conversation with a young coworker who had just turned 17. I felt disgusted. I am pregnant with our first and I had left my job because I was put on medical leave due to complications.

I feel trapped. I don't believe I love him as a husband anymore. I have no family support on either side of my family so I have no place to go. I don't want to be with him, I don't want to live with him but I am so dependant on him that I feel like I have no choice. I am considering just using my husband as a means of escape. I'm currently enrolled in college but I think I'll take a break from my academics and go back to cosmetology school and reinstate my licenses and then work until I have enough money to leave. All of this will take at least a year.

Is this really okay. Is it really okay for me to lie to my husband to get myself out?
