I am in a similar situation. My daughter was such an easy teenager through high school. She was very studious, showed little rebellion, and we were, I thought, very close. But she came back after a year at college with a very rude and disrespectful attitude. I told her I wasn't going to accept that, well actually I did get angry and yell, and she told me she was leaving. She has not been back.
She is 19 now and stays at college, which is only about an hour from my home. She takes weeks to answer my e-mails and phone calls. Then she says her phone is not working properly and she's been busy. I offer to help with a new phone for her and she tells me, quite curtly, "That is not your responsibility."
When she talks to me she is always very curt and distant. She makes plans to see her little sister (age 9) when her sister is with my ex-husband so she doesn't have to see me. She treats me with distain and disrespect.
I have beat myself up over and over again because of this. Sometimes I blame myself, sometimes I blame her, and sometimes I chalk it up to immaturity. But whatever the reason, it hurts.
But I have been reading a lot of posts tonight, on this and other sites, about other mom's in similar situations. It comforts me somewhat to know I am not alone, and this is at least somewhat typical.
And I understand that probably the only thing I can do about the situation is to protect myself from her rude and disrespectful behavior, just like I would protect myself from this treatment with any other human being. Because she is my daughter, I want to fix it and make it better, but I can't. I can only protect myself.
So I am going to try to draw boundaries and keep my distance until she is ready to come to me. Please pray for me, as I will need the help! And prayers back to all of you, too.
