Is this bad

So I split with my ex last November and it was tough I missed him for the longest time and took ages to feel better again. Sometimes I do still get down points but I'm a lot better. Anyway I've been on a couple dates in the past two months but I just don't feel anything for them. Is there something wrong with me? They were nice enough guys and got on well with them in person, good conversation etc, but I felt no chemistry or romantic feelings in person compared to when we were texting. I feel a bit like I have a problem, when I met my ex who was my first proper relationship there was sparks I liked him so much and it was magical. Unfortunately I haven't had that since. Is there something wrong, am I not emotionally available or something 😣
