Unsure How I Should React......Need Advice

Today I saw somebody that I havn’t seen in just over 3 months. We’ve had quite a bad past but seeing and hugging her today made me feel happy etc. I really want to try and make up with her but at the same time I don’t want to try and it ending up going to like what it was months ago. I really un-sure what I should do. Should I try and talk to her, tell her how I feel and try make up again or?

Please serious answer only.

Thanks.
