To date him or not to date him

Hey guys so my ex and I broke up almost a year ago and we talked on and off for a few months and decided to stay friends. He said he wasn’t ready to be in a relationship but I’m honestly not sure if that was ever true. 🤷🏼‍♀️ we didn’t talk for like six months and then a few weeks ago we talked again for a few days, I stopped talking to him because I really didn’t know how to think of him as a friend still even though it’s been so long and I didn’t want to get feelings that where not going to go anywhere serious. I’m not really the kind of girl who’s okay either just casual dating, I’d rather just be friends with someone or stay single until I meet the right one.

Anyways, my mom wants to introduce me to her best friends son, I know her best friend pretty well and she has made comments before like she really wants her son to meet me. I have not met him but we are planning on getting our families together for a dinner so we can meet. We are both the same age 23, we both are kinda in the same place in life with college and work. He seems like an honestly wonderful guy.

Would this be a bad idea for me to meet someone new considering where I am with my ex? I do feel like I still have feelings for my ex. But at the same time, if he doesn’t step up then nothing would happen nor do I think he will step up. he was the one who let me down so I’m not making any effort to someone who doesn’t know my worth. I care for him still but I don’t see myself ever not caring for him either honestly. I’m okay with knowing he is probably out there dating too and I do hope he finds someone who makes him happy. I know that my feelings toward him are invalid, but I hate how it gives me second thoughts about meeting someone new, someone who actually could be really good for me, I don’t know how to snap out of that. I don’t want to let someone down either. Should I cancel the dinner or just meet the guy and see what happens?
