Last night my partner asked a few questions about marriage. My mom officially freaked out about it and banned her from talking to me. Why is she interfering so much, is there something wrong? Even though there’s nothing going on between me and the person I love, being under such pressure stresses me out.
my mom did the same, she would even criticize us spending time together with my girlfriend. then I sat down and talked openly with her, it was hard but she got used to it 
It’s not surprising that your mom gets tense when someone talks about marriage without considering their age. Families tend to be a bit cautious, so I think you should question it 
This much reaction seems a bit excessive. Your partner just asked a question, why is their mother completely banning them from talking? It feels like an overreaction to me 
In such situations, try to calmly express your feelings to your mother. This state of prohibition will only suffocate you more, but try to stay calm without shouting. Perhaps you and your partner can explain it to her together.
What context did your partner ask those questions in? Was there a serious preparation vibe, or did it just develop casually?
@pazardandondum, there wasn’t actually a serious situation; they just asked out of curiosity. In fact, my mom thinks they are a good person, but they are very sensitive about such topics.
@kahvebitmeden you’re saying ‘query it’, but with that logic everyone would be a skeptic. What was he supposed to do, just finish it without any questions? 
give it a little time, sometimes the initial reactions can be harsh.
I had experienced the same thing; my crisis had gotten even worse. In the end, my girlfriend sat down with my mom and spoke openly, and after that, my mom softened a bit.
I think the issue isn’t with your partner, but with your mother’s sensitivity. If she’s only reacting with fear to questions, the real issue lies in the insecurities she may have faced in the past or her own anxieties. Without addressing those, your partner’s talking won’t change much. Where is this excessive reaction coming from?
I think the real issue isn’t your mother’s concern about your girlfriend, but rather the control dynamic she has with you. Is she this sensitive in other situations too, or is it just in relation to your romantic life? Take a look.
