Hi Stephanie,
You shouldn’t keep talking to him. Your feelings for him would only get deeper if you do.
You could easily tell yourself that he will eventually come around to having feelings for you if you just stuck it out, but that is unlikely.
He has told you that he talks to other girls. This means that he may be doing exactly what he is doing with you, with them.
In essence, he is calling them everyday and hanging out or going on dates multiple times a week.
Some may also sleep over at his house.
He has his attention on several girls which leaves little room for him to develop feelings for you specifically.
It is best to get yourself out of this situation before your feelings for him become so intense that you find it impossible to get yourself out.
