Is it possible to love my son more than anything but also regret so much?

I love my son so much my heart hurts. But I regret marrying my husband. I regret marrying into his family. I want to just pick up my baby and run. I'm sick of him not getting properly taken care of when my husband or his family has him. I hate being so sick to my stomach when I leave because I know my husband will stick him in front of the TV and only change him once. His family just constantly tries to put him to sleep. I hate it. I'm really feeling like I can't deal with the drama anymore. I want to just take my sweet baby and disappear.
