How do I (22M) introduce the concept of marrying my gf (22F) for marriage?

Not right away but I plan to get married after about 4 years.

We've been dating for about 1.5 years now. We're both serious about marriage and our socioeconomics match to a great extent. We have similar goals in life. We did Long-distance for about 11 months. Then I decided to shift to the city where she works and I work from there. Both of our parents back home at least know us, as good friends.

Her parents are kind of agreeing on our marriage in a way that they seek the assurance that they can see their daughter marrying me after a few years so they don't have to worry about looking for a groom for her on their own.

My parents (who had a very early arranged marriage) are very emotionally attached to me, to the point that even dating someone would be such a big deal for them. They know about her but my mom has warned me against her a few times, probably since I didn't have such good luck with women in my past. My mom majorly is very protective of me and she constantly reminds me to stay away from women and focus on my career.

We're both career-wise IT freshers, both earning in the 50-60k range in fairly renowned companies. I do invest as a hobby and have a decent portfolio of about 15 lakhs. I get guidance from my dad in stocks and have started saving up for various future events in my life.

Right before the day that we decided we'd live together, she got a call from her mom with the concern whether she has a guy in her life and if that is so, should they not look for a groom for her? I get her parent's concerns and it seems logical because if you don't plan it like that, that might delay her marriage for a few years if we end up not being together.

My concern is how do I approach my parents with this?

What I suspect that I'll be hit with is that -

• "Why hurry so much can't you wait?" Sure and I'm not saying I'll marry right away. But I'm just informing you that there is a girl that I can imagine myself spending the rest of my life with.

• "Focus on your career for now". Who says I'm not doing that? I've been more focused than ever, ever since I met her.

• "No you can't marry her" or "marry someone of our choice" and what be happy? How is leaving someone you love and marrying some stranger better?

So you see they get very emotional about these things. Especially my mom. The kind of relationship I have with my dad is that I go to my dad with a proposal (mostly a career move or financial or social advice) "I wanna do this, whatever do you suggest" and he provides his best advice and I'm getting this liberty to choose whether to follow that or not, in most cases. I'm not sure however what will their reaction be in the case of my marriage.

What we've concluded for now is that I talk to my dad first about this and then if he agreed to it, he approached my mom with the same.

If that is successful, I would wanna see both sets of parents agreeing on the marriage (Neither we nor our parents care much about the rest of our families, or that's what we think). We're both open to court marriage.

I seek some examples or scenarios on how can I bring up this to my parents, in a way that goes in a positive direction.
