Ok so earlier this week i asked a question for help on my mother in law that keeps calling.. well since?

thursday she has been calling and texting us wanting us to come over all weekend so our kids could see her husband.. why does she think we have to come over there all the time and call my husband just to check in and make sure everything is okay.. i dont think im being paraniod my she keeps leaving me voicemails on my phone. my husband told her it was broke and shes just calling calling calling. i dont know if i should answer or try to answer her calls or reply to her text or should i just let her think my phone is not reciving anything? My husband odviously isnt too worried about it since he hasnt asked if she has called or anything. Im just not to sure what to do. When we were seperated a little over a month ago she wouldnt reply to my text or even tell my husband i would call. This is just really frusterating to me. She just even instant messaged him on his account... I dont want my husband to be mad at me its not like im with-holding her son or anything he can use the phone if he wants its just crazy i believe she is calling to see if him and i are fighting if he needs her to come and get him or just to make him feel sorry for her probably gonna tell him how shes broke or something im not sure but im getting upset and i really dont know what to do.. she doesnt need to talk to him everyday RIGHT? We are a family it kida makes me feel like she wants to be all in our lifes we never have time together because she just wont stop.. Does anyone have any advice for me? I just need to know what i should do. And please nothing rude. Thanks
