Unsure on wanting a relationship

I have been single for like 2 years and the guy I have been seeing has been single for like 3 years.

He’s a nice guy but I don’t feel that “spark”... I like him but I don’t want to settle.

He asked me to be his GF this evening and I was honest and said we should keep getting to know each other because right now I’m not sure. I got used to being single, so a relationship is weird to me.

Plus I’m 5’11 and he’s 5’9 and everyone makes fun. I just don’t know... someone talk to me about this. 😕

Judgement or unnecessary responses will be ignored.

I have been grieving the loss of my son in February and don’t need any judgment.
