I'm scared of being abandoned.

I'm so heart broken. I feel like I post here almost every day complaining about my relationship and I'm sorry. I just don't have anyone to talk to :(

My boyfriend and I broke up and we ended up getting back together. I got pregnant the first time we had sex after we got back together. I'm now 14 weeks. He has an alcohol problem, not as in he drinks too much, but when he drinks, he gets mean. He's also on steroids. We've had a rough couple of weeks but we did decide to keep the baby.

He hates my dog because she barks. She barks because she's being made to stay in the garage in her cage because she hasn't had a bath. (She's not dirty, she's just 12 years old and smelly as most old dogs are). I'm not allowed to bath her in the house and my dog groomer was booked this past weekend. I put her out on a leash this morning and put her outside while I got ready for work so she would have some time out of her cage. He got mad and said "That's my leash". I thought it was mine and said so, but who really cares? We both have dogs, he doesn't use it on his, whats the big deal? He's using my charger. Who freaking cares? We've been together for 2 1/2 years.... He started yelling at me over me using his leash and I asked what the big deal was? He said that its because he hates my dog. I've had to ask my mom to take my 12 year old dog who has cancer, who loves me more than anything ever has loved me, because he's just being a jerk. We've also fought over me not making his lunches, though he keeps me out until 11 at night on Sunday when I had planned on making them. That was the night he fought with me until 3 in the morning, accusing me of sleeping with my ex husband over a year ago because he said I "smelled like I had sex" when we had sex that night.

We didn't leave the house on good terms. He's messaged me telling me he needs a break from me. That we don't get along. Sunday night, we were at his bosses house for dinner and he apparently has made a big deal to him (and did infront of me that night too) that he is too hard on me. Other people are seeing it, just not him. Him yelling at me over using his leash is not "us not getting along". Why can't he see this? I came here, found an awesome job... we are adults expecting a child... I don't see how we just "take a break". Its not like I can stay with friends or family. I just moved here in March from 4.5 hours away. I'm scared that I'm being abandoned. I'm so scared of everything. I want this to work. When we are happy, we are beyond happy. Those moments are coming so few and far between now. Even if I wasn't pregnant, I wouldn't want to throw in the towel. I don't know what to do :(
