We broke up and its hell

My boyfriend and I have been together almost 3 years. We have 2 children together. Weve had our fair share of ups and downs. The last few months Ive pretty much given up on the relationship. Hes drained me. Hes made me feel a way about myself ive never felt. Most days I hate myself and cant get out of bed. Ive pushed. So hard. Last night I asked him who was giving it to since it had been over a month since he touched me. He replied "Not you." In the meanest way. I cried myself to sleep. I just wanted him to love me. But, I got up this morning and made a few phone calls. Ive got this little town 45 minutes from me that I call my happy place. Theres literally 1 gas station for MILES. Its beautiful. There are maybe 300 people that actually live there. Its so quiet. Anyways I found a job that provides housing for cheap. The job I found is what I do for a loving anyways and its my calling. So, its just a win win. I get home and my sister and mom have totally downed me about my decision. My sister cant have kids so I ended up getting pregnant for her. Im only like 13 weeks but she keeps saying I need to take her into consideration since she already has to drive 5 hours for appts and thats an extra 45 minute drive. Her and my mom both keeps telling me I need to think about my children and suck it up until Christmas because ill mind fuck them if I dont. I was so proud of myself. I didnt sit around and cry and complain about the break up. I got up and took care of business. Now im getting so much hell and already im feeling discouraged.
