Is this normal or desperation?

I met a guy online and really felt like he was the loml even though we were just speaking.it’s been 3months we stopped speaking because he said he has ‘other options’ but it physically hurts my heart and can’t sleep at night for this guy. Im in my late 20s and he is in his early 30s and I really felt like he was the guy I was going to build my family with. I can’t take this anymore.
