I'm sorry you're going through all this rubbish!
To answer your question, yes, unfortunately I have had (and still do have) similar experiences! I'm no longer 'together' with my long-term boyfriend (who also proposed), and I just cannot maintain romantic relationships for very long for this reason.. it's really hard, but I just know in my gut that not pursuing that kind of relationship is the best thing for me right now. That being said, I also have similar issues with my family and friends not allowing me any time to try and help myself. It's really tough, isn't it?!
We just have to establish our priorities and stick to our guns.. it's a shame that so many of the people who should support us simply don't, but such is life, I guess!

Thank goodness for this forum, 'ey?!
