Need advice

Ginny • Hello I'm 25 and loving my life. We are expecting a little boy and I'm in love with this baby.
So through out this pregnancy I've seen everyone for their true colors. I've had my best friends tell me that they will help me if I asked but one has seriously not talked to me at all. I text her asking how she is doing, if she wouldn't mind helping me with groceries and see each other on a weekend to weekend basis when we can....But she has not texted me at all...or called or anything. What do I do? I love this girl like she is my sister. She went through a very bad break but keeps going back to the guy. He cheated on her twice and both times I was there. I was her shoulder to cry on and did everything in my power to make things better for her...I just hate to give up on her.
