Toxic relationship

Getting out of toxic relationship is way harder than it’s thought to be.... I use to be the girl who would say “why doesn’t she just leave”, “why does she stay with him if she’s so unhappy”, “she could do waaay better” and now I’m the girl who asks myself “how do I get out”, “will he change”, “he does nice things, maybe I’m just being dramatic”.... I’ve been with my boyfriend for almost four years, he’s helped raise my son as his own and we have a daughter together. I honestly don’t know what to do anymore. I feel like I need to get away from him but then I wonder if I’m just overreacting and being sensitive. I’m also super scared to leave because I have two littles I would have to provide for and with him they have everything they need and want. I feel so lost 😔 I don’t know what to think or feel anymore....
