Help me validate my decision

So, I’ve been with my boyfriend for almost 2 years . We have lived together for more than a year now. We always seem to have the same Recurring arguments. At the beginning of the relationship he basically made me cut ties with with people I had a past with, but continued to just be FRIENDS . He didn’t want me to go out to social gatherings with my girlfriends ex: bachelorette or even going out for drinks with them . Also , He does not like the father of my 4 year old son because he sometimes does not pick him up when he is supposed to and he does not help me financially . I honestly do not like confrontations and hate arguing . I am at peace that the father of my son is a shitty father . All I care is that my son has a relationship with his dad even if he’s not the best role model . I feel like my boyfriend has gotten so controlling to the point where I can’t co-parent because he will always make negative comments about my son’s dad and when my ex picks up my son , my boyfriend will go out and take him to him . Lastly , my boyfriend wants to be very strict when it comes to parenting my son . I am not ok with what he want and I have told him plenty of times . So I decided to leave him last Friday . I just need some advice . Making sure I made the right decision. I feel we as women can get Caught up in unhealthy relationships and I CAUGHT MYSELF . It is very difficult, but i just need that support .
