Is it normal to still love a deceased first boyfriend while married?

Even though I've been married for 4 years and we have 2 year-old twin daughters, (ages 34 and he's 37), my first boyfriend still holds a place in my heart. The reason I don't refer him to as an ex boyfriend is because I lost him tragically. I'm literally alive beccause of him; he didn't make it. He drown at the beach. They never even found his body but I know he's dead. He got in the way and handed me over to a lifeguard and 2 rescuer. Then within a few moments later, I saw him getting dragged at sea and he never resurfaced. We were 18 year-old HS seniors at the time, we each other's first date, first kiss, first relationship, first experience.

I'll never know how life would've been if he didn't perish. Perhaps we might have broken up years later or maybe we would've been married, who knows. The point is yeah I never forgot him. I still visit his grave some days. I love my husband but I also love him. Other days I feel guilty for not ever getting over him? It would've been different if he didn't die and we break up years later but the relationship never ended naturally. Can you have two loves while married? Is this normal?

At the same time, I couldn't continue going childless forever. I still wanted to get married and have kids.
