I don't feel anything when I pray - what should I do?

Assalamu alaikum. I had a situationship that ended two months ago with a Muslim man; the main reason he gave for leaving was that I didn't pray. A few days before the breakup I prayed Asr for the first time in God knows how many years (I was born in a Muslim household but never learned how to pray) and I asked Allah to guide me and to keep me away from him if it wasn't meant to be. After that I started praying consistently for two months - some days all five prayers, other days three. For the first month I only knew two surahs, Al-Ikhlas and Al-Kawthar, and later I learned Al-Falaq, An-Nas, and Al-Masad and read their meanings. I don't have them memorized perfectly but I understand what they're about. The problem is I don't feel anything when I pray. Maybe I do and I just don't recognize it. My mind wanders: sometimes I think about an Islamic podcast I listened to, sometimes about that man - not because I want him back but because I picture him seeing me pray (and I worry that's prideful, so I tell myself not to be egotistical about it). Other times I suspect I only pray because he left me over prayer, like I'm trying to prove something to myself or him. Some moments I reflect on the Day of Judgment, imagining the scales and my deeds, or picture myself in prostration and suddenly my eyes well up. When I read the translation of Al-Fatiha and reached the phrase about “those who are astray,” I felt tears coming. Have my sins made my heart so hard? I used to think I was a decent person by worldly standards - I never smoked or drank and avoided things like that. Is my heart too attached to this life? When people say they’re in love with Allah, I can’t imagine feeling that way. I make dua and ask Allah to soften my heart toward Him, but still I don't always feel anything, and I tell Him He knows best. Jazakum Allahu khairan for reading. Edit: Even as I write this I wonder if I should post it - am I seeking sympathy or trying to convince myself I'm doing the right thing? Also English isn't my first language, so sorry for any mistakes.
