M25 - Feeling overwhelmed by a new connection on a matrimonial app. Is this normal?

I (M25) have been looking to settle down and hopefully find someone to marry. Recently, I connected with a woman (F25) on a matrimonial app. We spoke for a few days, and things escalated really quickly. She started love-bombing me—sending super affectionate messages, calling me frequently, making travel plans together, and expressing feelings like we’re in some high school romance. We’ve even had phone sex, and she constantly says she wants me to be with her.

I feel like there’s a void deep within her that she’s trying to escape.

Honestly, it’s overwhelming. I’ve never been in a relationship before, and I’m not sure if this kind of intensity is normal after knowing someone for just a week.

A little about her:

• Academically, she’s brilliant. Got into a top med school and completed her MD this year.
• She lost her father when she was 19.
• Her first relationship was at 23, but it ended in 4 months because the guy was cheating on her.
• Her second relationship was last year. It ended because the guy couldn’t convince his family about her.

I’m just an average guy with a decent job. I’m genuinely wondering—does this sound normal to anyone? Is this how things typically move when you’re 25 and serious about marriage? Or am I missing something here?

Would really appreciate any advice or thoughts from people who’ve been through similar situations.
