How does it feel to not be broken?

I always thought my ex(25F) would be the one I (28M) would spend the rest of my life with. After 7 yrs of being together we called it off. It has been 5 months and I am still struggling at times, emotionally. Late at nights I scroll through this community to find ways to cope up and some advises have really helped. But one thing has been standing out like a thorn – it's a feeling like I have been broken somehow and I need to reinvent myself. Questions like whether will I be able to form that same bond with another person as I had with my ex, haunt me. Will I be able to love someone? Some days the chain of thoughts goes even sadder to will anyone be able to love a broken me? So I just wanted to ask everyone out there – what it like not getting your heart broken? Marrying the person of your dreams? What's it like not having to reinvent yourself? To be called not broken?

TL;DR – Asking a question about what's it like not to be broken, not to get hurt from the perspective of a recent breakup.

P.S – If this question is too lame I will politely delete it.
