Lost and confused

I’m in an amazing relationship. I love my boyfriend very much.

My ex, is also in another relationship.

He reached out to me the other day.

I never stopped loving him. Our breakup was complicated. But the first time I saw my ex I loved him. Immediately. It was literally that stupid cliche movie scene love at first sight. But it truly was.

He told me last night he still loved me and we talked for two hours about how we felt about each other. But don’t know what to do.

Being in love with two people is making me want to die.

We are talking about seeing each other soon...

I NEED ADVICE BEFORE I RUIN MY LIFE.
