"Normal relationship"

I was in a bad relationship for four years, verbal and abusive. Made to have sex when I didn't want too, stayed with him because I loved him and was afraid not only of him but of being alone. I am now in a good relationship but I freak out as soon as we argue or something because of what happened in my previous relationship. We have been together 6months and tbh I really don't know what a normal and healthy relationship is? Please help so I can stop feaking out and stressing myself out about just having a argument etc. He treats me right, looks after me and supports me etc it's different to what I had in the four year relationship. I am currently seeing phyco therapist to help me through the things my ex out me through. Feel like I'm pushing my partner now away because in general I'm just scared and I really care and like this guy he's husband and father material so I don't wanna lose him! Please help!!
