<p>Old, we only have half the story here. I'll bet you a pitcher of martinis that if you asked the GF's mother about the OP her version would be: "I love this kid like he's my own. He goes off to college and is miserable and what are his own parents doing for him? Nothing! My D and I are prepared to visit him as often as we can to help him adjust and not feel so isolated. Do his parents appreciate that? No! They think I"m the witch who won't leave their son alone. He loves my daughter and we love him like he's a member of the family. They are so judgmental; they just don't get him. College isn't for everyone; he can move back home and find a place that's a better fit for him. He really hates it up where he is, what kind of parents don't see that?"</p>
<p>So I'm not even prepared to evaluate what's what here. I can tell you that since the OP is footing the bills for S's college, and presumably has raised him, loved him, etc. she's the one who is responsible for getting him launched into adulthood. But I have no doubt that to the GF's mom, the OP is engaging in some really tough love which she may not find to her liking. Best for everyone involved (especially the son here, who still has to get through finals with some decent grades if he hopes to transfer some day) if the OP keeps the issue of the GF, Mom, who to date and who not, etc. out of the picture.</p>
