Thinking about leaving

So me and my significant other just do not get along .started out his friends a year-and a 1/2 ago I was dating his best-friend he cheated on me with my friend so that's how I ended up sleeping with my significant other .long story short I got prego he didn't want to claim his son...was a single mom for first 3 months...we then decided to be a family. Moved in together...basically forced our relationship...now 6 months later we just fight every other day and I want to take my son and live in Virginia with my family. This is easier said then done bc I allowed myself to depend on him 100% financially (big no no) and I also don't want to hurt my son in the the long run. Also my dad is involved bc he lives with us and is in his 70s so if I move he has to find a place to live bc he does not want to live in Virginia. I don't want to put him thru that. I also love my SO and am scared I will change my mind and I cannot do that if I make this decision....but also don't know if I am in love or just love him bc he takes care of us.
