Forced love?

So I feel super weird about my mother. I’m 27M caring, helpful to others, and pretty dang successful. I’ve made my fair share of mistakes in life but I learn and grow daily… (Just to preface)…anyway, every time I text my mom she has to end the conversation with “I love you!” And gets offended if it’s not reciprocated (which it almost always). There’s been a time or two where it wasn’t and she’d just send the text again in bold…Now I know I should feel fortunate or whatever because not everyone has this in their life…But it’s the fact that she’s always been super manipulative towards me. She still tries to contradict how my life goes and I subtly hate her in certain ways. She’s extremely nosey and feels entitled to be in every aspect of my life. She gives constant unwarranted advice and still treats me like a kid. Anytime I have a different opinion she somehow “punishes” me for it. I just feel obligated to say it back but honestly, I resent every time I do. She was a pretty “extreme”parent growing up and has never admitted she made mistakes. I feel like I should’ve outgrown this feeling but somehow it still lingers in my chest. So yeah I kinda hate my own mother and don’t know what to do about it.
