Pregnant in a unhappy relationship!!

I am 14 weeks pregnant in a relationship that has not been working for a while. Unfortunately  when I decide to leave and go our separate ways and that's when I found out I was pregnant. I've done almost about everything to make my relationship work but dealing with a person that suffers from depression and severe trust issue is one of the hardest thing I've had to do. Before you guys ask yes I was on birth control but caught the flu went on antibiotic and as pre my doctor mostly likely is when I got pregnant. Everyday I try saying today will be better but I won't lie to myself is just not the same. Over all is bad our sex is the worst and I'm not sure if is the hormones but I just prefer to do without. I am strong person and know no matter what I have to stay strong for my kids but wow. Having a baby with a person I just do not see myself with is hard.
