Hi there, I have honestly experienced a very similar situation but it was with a friend I had feelings for. If you know deep down it is the right thing to do, even though it hurts for awhile it is the right thing to do. Just because it hurts now does not mean it is the wrong decision. Obviously you feel hurt, its a normal reaction to the situation if you didn’t feel anything that would be a worry. If this problem of hers will continue effecting the relationship then there can be no relationship it is simple as that/. Trust me, I have felt a lot of heartbreak and even though it hurts so terribly right now and its all you can think about, it will get better, I promise, there will be a day when you no longer feel that sadness and you will be able to properly move on with your life. from your replies I can tell that even though you are sad some part of you is glad that you made this decision and deep down inside you know it was the right thing to do for both you and her, ( it might help he realise that getting help is the best thing)
