maybe tgey r little busy....they will sure catch up u qickly...dont worry🙂
Talk to them and figure out why they are doing it. I agree with the above person as they may be busy.
have you tried talking to them about how you feel or perhaps writing a letter to them about it and explaining what they do in order to make you feel ignored and suggest that even if they are busy perhaps you all could agree that such a time on such a day is when you will make contact with each other to help prevent you feeling like you do? sometime i find just having a quick chat in a busy schedule or letter writing so they can read when they do have a mintue spare and being honest about how you feel without a such pointing fingers for blame can help make others see a situation perhaps they havent even realised. Im sure they will try rectify this and include you once they realise
