Am I a horrible person for being in a relationship?

I'm legally married but I have been separated since last year around November. My husband was abusive and a cheater who put me through so much. We have a 10 month old daughter who he hasn't seen or done anything for her since last year. I met an amazing guy in the beginning of February and he asked me to be his girlfriend yesterday. He treats me the way I should be treated and he doesn't just buy me things. He also gets my daughter stuff and he's better with her than her own dad. I honestly love this man but I feel shitty for feeling this way and I'm not even divorced yet. I'm also scared to tell my family I'm seeing someone because I'm scared they'll judge me. Am I shitty or do I deserve to be happy? I'm almost 24 years old so I'm old enough to make decisions but I also care what my parents think. The rest aren't that important
