Broken.....

I just broke up with my boyfriend a couple days ago.....and just found out I'm pregnant...we have two kids together already but their from a past relationship. This is baby would be his first... We broke up because we have been fighting ALOT lately and it was starting to be just like my old relationship was in the beginning. I got scared that he was just like my ex. I dont know what to do i love him with all my heart but. He makes it so hard for me to trust him. He has lied to me multiple times. I dont see the point of being together if there is no trust but now idk what to do about this pregnancy......
