My long time partner has fallen in love with someone else and wants to be with us both together. I am open to the idea but she doesn’t connect with me the way she did before meeting him and it is hard for me to feel included. I love her more than anything but my heart hurts watching her do the things with him that she used to do with me. I don’t know whether to keep trying to be with them, to be with her but not with him, to be with her but look for a new partner of my own as well, or to end the relationship all together.
