Maybe you can help me understand

8 years with my gf (same sex relationship) and I messed up in the beginning now she is just holding onto my part and will not let it go. Well moral of the story she thought I’d be funny to go cheat and now she’s pregnant. And she makes me feel like I’m in the wrong for making comments like “you have nothing to worry about my way” I should have left her but we have a two year old together and I would never want to leave her side. Ugh I’m so annoyed.
