Friendship woes

I have a close friend and we know each other for 10 over years. However I find she kind of bo liao in the sense that little things also wanna complain. We got pregnant almost same time and our sons are just few months apart. She always like to boast about her son and her life too. I've cut contact a few times with her and the latest move being 1 year ago. She did keep msging me and ask what happened. After that she stopped. We bumped into each other once but never talk. 1 year later she msg me again and ask I'm still angry? My question is should I contact her back? I feel touched that I ignored her so long she still keep msg me. But the thing is i feel my life is rather peaceful when we are not in contact. 😂 what should I do? This cycle of me cut contact and get back in contact keeps repeating. However i do feel quite happy to see her that day. But at the same time I feel if contact her back my life will not be as peaceful? 😅Or maybe cuz im the type who dont like to bitch. She will boast about how smart her son is 3 years old and boast about her life where she went to eat etc. I ever hint her before don't have to tell me so much about her life almost everyday but she said cuz im her best friend and she just want to share with me. Anyone #pleasehelp
