My mum is making me feel giulty?

Hello everybody! I want to idk maybe vent and ask if this has happened to anyone else and what did you do?

(Just for the info, i am now 21)

Long story short, like 5-6 years ago my mum left my abusive and alcoholic father. After that me and her were living alone in a small apartment. We became very close, we were like best friends, she wasnt doing very well so i was the shoulder she could lean to when she needed that. (At this time i was like 15-16yo) My childhood was okay but it had dark moments too. I hated living in my home country, i had so many painful moments in there that i wanted to run away - i felt not good in my head nor my body. Two years ago i moved to my dream country (with my boyfriend) and i am so happy being here, i like everything about it, here it feels like i can finally breathe and not think about the painful past.

So now where it starts. I very much get it that i moved out like... from no where, i think she never expected me to do that (because according to her, i am a small mouse under leaves that is scared of society, scared to do things on my own, i am not talking with people which apperantly makes me weird - but i was just introverted) and she thought i will always be with her. I do feel bad that i left like that, but i do need to start my own life, right? So anyways, now for the past 2 years my mum has been asking 'are you coming back home, maybe you need to come here and work here, so its easier, how are you going to do there you dont know anyone, you dont have friends there, its going to be so hard for you because you are quiet, i will keep your clothes here in case you will come here for forever' and so on. Me and my man went to visit her in September, everything was good, but there were moments where she makes me feel bad and guilty that i want to live in another country and i want to create my life there? One day we were sitting by the table and my grandmother asked me if i want to stay here (in my home country) and i very much said a big no i do not want to be here (they have heard this before like 100 times but they keep asking), we all laughed it off but my mom literally got so mad at me that i said this, everyone went silent around the table, she looked at me like i said something very bad or offensive. I felt also so angry but guilty at the same time? Like why is she doing this? I understand that she misses me and so on, but come on? I have never ever said anything against my mum, never talked back, so it is pretty hard to deal with this.

Sorry for this maybe nonsense post, but i just wanted to ask someone, has any of you experienced this and how did you dealt with it? I talk to my mum, we have a good connection, but sometimes she just puts these kind of comments out of nowhere that makes me feel bad and affects my stress and anxiety, that 'omg maybe she is right, it wont be good in here, i am too quiet to live my own life' and so on.
