Not feeling that I’m made for a relationship

Is anyone else in a relationship and having a hard time??

I’ve never been in a relationship until 6 months ago when I met a great guy online.

The last 6 months have been amazing and now I’m just confused and wondering if I should move forward.

We text everyday but I just kind of feel like he’s pulling back and maybe not putting a lot of effort in. We don’t live together obvi but we are eachother at least 2 times a week.

The relationship has been innocent and sweet but now I’m like over thinking and questioning my worth. It’s driving me crazy. I’m now thinking......is this even worth it???? I feel so insecure all of sudden and I’m not sure why? I never was insecure before this relationship and had an amazing relationship with myself first.

Am I over thinking? He’s a great guy so why am I going crazy?
