Advice anyone ?

Hey everyone I’m here to get some type of advice. Well I have a friend. Her and I been friends for about a year. We talk a lot through text etc. She’s a very nice person. All she really talks about is her and her boyfriend problems. I mean I listen etc... but now I don’t know what much to say.. I mean it’s allllll she talks about. Maybe a couple times she will ask what I’m doing etc.....

Well she told me about 4x already that she would come over to hangout etc. The day come and seems like they have a fight and she doesn’t ever say she can’t come she just doesn’t mention it about not coming over. Other times she will say she’s tired or “cramps”. I mean we talk everyday and it’s 99% about him she keeps taking about how he is doing this and that. I’m trying to be a good friend but it’s getting old. The other thing that bothers me is she always will say she coming to hangout and then just doesnt. I’m tired of being here for people like that.. it’s like is this really even a friend for me etc... what do I do?????
