Teen mom with boyfriend and dog stress…

I have a wonderful ~Spoiled clingy~ little dog..I fully live with my boyfriend and my dog in our own apartment(Legally aloud too live by our selfs)

Well I’m a pregnant teen mom so I’m already under so much stress BUT my boyfriend and dog do not help…I’ve had my dog for 3 years and only been with my boyfriend for 9 months and my boyfriend HATES my dog..he has never physically hurt my dog but he will get visibly very angry with my dog and I can’t leave my boyfriend because I’m financially dependent on him and I’m pregnant with our baby! I and my boyfriend have a very happy healthy relationship besides how he treats my dog. I don’t know what too do with the two of them.

The other night I asked my boyfriend too take my dog out and they were gone for 20 minutes..I walk outside and my dog is cowering in the corner very scared while my boyfriend is angrily getting his collar back on,I yelled at him too get off of my dog and stop being so rough and my boyfriend stormed too his car saying he is going on a car ride.

I just am so lost on what too do because I feel like it’s so difficult too live with them acting like this but I love them both so very much..PLEASE I need advice on what too do..
