I dont want to do it on face but in the long run I want to have no contact with this selfish frd I have .Whenever she needs us , She calls us anytime and we always help her .Recently for some silly application my husband was on phone with her for 3 hours just to explain her the details .Now , Yesterday I asked her to just help me around in my los birthday party she refused and said She cant help me since she will be tired after work .Really ? Also many times she has taken me for granted . What to do ? In reality I want to block her but cant do that since her husband is my husband are good frds .Please help
