How to get closer to my boyfriend

My boyfriend used to always want to hang out with me and want to talk to me and now he seems very uninterested.

he recently got a job and I started gymnastics training and I understand that but he never wants to try to find time to spend with me.

We have a lot of sexual chemistry and a lot of the time we go together like brownies and ice cream and when we fight we’re still very playful.

i’m pretty insecure and need a lot of validation in a relationship and I want to talk to him but we can never find the time. We’re both also very terrible at texting😬

Am I just being clingy or...

I also feel like I just know nothing about him. he used to feel the same way about me but he doesn’t get very emotional with me like he used to.
