why doesnt my sister speak to me?

[Ashley M]

my sister is in a relationship with a man who is 32 and she is 22. they have a 1 yr old son, my nephew. we used to be extremely close until she started seeing this man. when she had the baby it seems like it got worse. she had to stop working because her boyfriend has a full time job and part time job and they dont have proper child care, so she stays home to take care of the baby, cooks, and cleans. i never got to fully know her boyfriend but i never really got good vibes whenever we hung out. shes told me he has been married 1 year and now is divorced and he has hit the woman he was with before. he seems very anal. likes his clothes hung up colored coordinated, towels folded a certain way and put away a certain way. she claims he said nothing but good things about me, but who knows whats really true as it wasnt said to my face. my sister is the type to hide what really goes on behind closed doors and make it seem like she has a picture perfect life. ive always been there for my sister through everything. i cant say she has always reciprocated the same back for me. one day we were close and then the next all lines of communication had stopped. she is still on my facebook and i check her activity . she posts lots of pictures of my nephew and her. ive even seen her post tags of her hanging out with friends with the baby. i never see posts about her boyfriend at all, they arent even facebook friends. ive reached out to tell her happy birthday and merry xmas and all she had to say back was same to u ive also changed my number and reached out to let her know i dont have hers and no response or reply like she could careless that im in her life. she even posted about my nephew having a 1st birthday and never invited me to the party. im tired of always reaching out to see what her problem is but being she has a child its like hes growing up not knowing who i am. it makes me sad because i have missed out on alot since he was about 6mos. first words, steps, birthday...etc. this isnt the first time , seems like she loses herself when she gets into a relationship. being that her boyfriend is older i feel hes not a good man because he seen the bond we had and i feel if he sees she isnt talking to me as much he should encourage her to do so. idk im lost. why does she treat me like this?

If you feel that there is something wrong try to establish communication with her again. Either way the major problem you suggested was you missed her.take the time to reestablish your Relationship. He may be dangerous and needs help, however you could be wrong so best thing to do is just get close.don't take no fokr an answer spend time with her talk with her share your life with her and she might do the same. Be good to the people she loves eg bf and son
Takes a lot of work but its all worth it.

You miss your sister.

All your concerns regarding your sister are probably well founded, but there isn't much you can do if she doesn't respond. The best you can do is exactly what you have already been doing. Let her know you're there for her. Keep in contact. She may not appreciate your efforts, but if she gets to a point where she needs to turn to someone for help, at least she'll still have a lifeline to you.
