Friend or Foe?

Hi mummies, I have this friend who gave birth few months later than me. My child is now 23 months old. This friend out of 10 WhatsApp and face to face conversations, she will boast about how smart her son is such as, at her son's age, he is very advanced can play kick scooter, can play swing independently(but once she came my house and we went downstairs her son can't swing at all), can bathe himself, wash his own hands, remove diaper, recognise boy and girl, she says her son and her niece PD are the same and she says her PD says her son is smarter than her niece(is there even PD that will say things like this?), than says her PD assess her son's brain during normal checkup to be 3 years old(is there even such assessment during a normal check up)and the list goes on. My son is still not talking yet, only occasionally one word at times and mostly making sounds. My friend's son is talking few words and according to her sentences now, and my friend asked me if my son is talking sentences as her son is. I've hinted her there is not a need for comparison as each baby have their different milestones. To me, what her son are good at(which my son already knows) but I don't boast to her. Also, there are things my son is good at but her son is not and vice versa. I gets really uncomfortable with the conversation each time. How our conversation always ended up about how smart her son is, for example, she will complain to me say her friend compares her kid with her son and she will go on to say how smart her son is to me or she will complain her husband pick on her son but she says he should be thankful their son is very smart can do etc. etc. etc and the list goes on to me. Also, our conversation always have her son as topic, but when I talk about how smart my son is once or twice(since she is always at it) she ignores what I said. Besides her son, she also likes to boast about her assets. Once she texted me she left her home without locking the door(she stays condo) and she says she have 8 rolex in her house so she called her guard to close the door for her. Do u think this kind of friend is consider friend? Overall, I have unfriended her before more than once but gets soft hearted each time she finds me back. When I did not contact her, I feel my life is peaceful. Do u think I should unfriend her once and for all? #pleasehelp #advicepls
