Not sure what to do! Not baby related technically

One of my old school friends had a baby last year and we got talking again on messenger as I know how hard and lonely it can be having babies and just wanted to lend an ear when she needed it. She fell out with two of my best friends a few years ago but she has never done any harm to me. They knew I had spoken to her as I had told them and seemed ok with it. She has invited me round to hers and I am conflicted as to whether I should go or not, and whether I should tell my friends 🙈 I don’t want them to think I’ve gone behind their backs. I always got on well with all my friends and haven’t fell out with any myself. I just don’t feel comfortable… what would you all do?
