Being new to Mumsnet, really could do with some advice/reassurance....my 17 year old son is in a 2 year relationship with a slightly older girl who is highly controlling. He wants out as he's been pulled in and blinded by first love but no longer sees his friends etc. Every time he tries to finish the relationship, she says something that means he runs back to her. That's where he has rushed off to tonight to 'sort things out'. I'm very anxious, want to get involved and really worried for him (and feel for her as she says she has no-one; her parents are against her, has no friends, and my son is all she's got). How involved do I get?? I have has some rational discussions with him but am getting more and more anxious about the whole situation. Thanks.
