Trying hard...as a different view on this...your therapist was right when she told you that the other person could not have entered into your life like that....but you must also evaluate your relationship with the other person...how does he feel about you? I suggest creating space between him and you as well....that way there will be less hurt in the long run....if things change....
I know this from sad experience....about two years ago...I was in love for the first time...with a woman who was a bit older than myself....she did love me too...but I was the rebound relationship...I was the one who could give her the emotional support she needed...plus at the time we came into each other's lives....we were both lost....I was in the midst of a breakdown...and very suicidal....she had lost many people dear to her....and was in the process of losing a 22 year old marriage....
She left him....and found a place and I practically moved in....started working again after being unemployed for 10 months...and things started looking up....but there were times when her husband would come over...and I would go home...that always tore at my heart....the times with her were so happy...and loving...but always tinged with sadness and pain....on all sides...then the day after christmas of that year...she told me she was going back to him....and my heart was torn to shreds...became very unstable....only composed on the surface....and the fact i was no longer on the meds did not help....had no insurance...and again was suicidal....then after a few months I cut off all contact with her...and many of our mutual friends....then finally after a year....we got back into contact....and now we have a friendship stronger than pain...stronger than ties of marriage....stronger than life itself....we are just friends...but we still love each other...it has only shifted....she is the friend of my soul...and always will be...in this life and the next...
sorry for getting off topic....just wanted to say my side....and I wish you the best.....
