You're in what I call a half n half relationship - it meets some of your legitimate needs, like having someone there, someone to do things with, someone to be involved with, but it doesn't meet others.
I don't think it will change because most of the men I've known who adored me, did so from the outset. It did not have to grow over time; bang and the feeling was there. In this case the feeling is not there, he has said that and he is looking at other women. When he meets someone he adores, he will relegate you to 'friend.'
If this is not what you want long term, then continuing is a waste of your time and heart. And like someone else said, that is on you.
I think most of us have done this, and they have all gone the same way, and hence we can see from the outside. You have let your heart grow fond of a man who doesn't want what you want and doesn't feel the way about you that you feel about him.
How much time are you going to waste? x
The best thing to do is go no contact, stick to it, be gutted for a few months and then start feeling better and go on to meet other men. At that stage, you need a list of values and criteria, and need to guard your heart and not make excuses for men. In this way you will protect yourself, date, but not give your heart to any men other than one who adored you the moment he set eyes on you and who wants to be in the same kind of relationship that you want. x
