We will have a chat tonight or on the weekend... the issue was that he still believed he had a chance... and I think what happened with them over the phone clearly shows him how things stand... it's been 4 months that they have been apart... and he knows about me... and I think he will finally have got the message... we will see... I have tried to keep it casual... and to be fair it is... we only see one another once, maybe twice a week... but my intentions are for something more serious... I find it hard, when I like someone, to keep something casual.

I can understand your feelings, and I don't know the girl, but can't help feeling giving the ex a chance, and filling him with false hope, instead of nipping this in the bud with him, is a red flag to pay attention to. That you cannot adjust to these facts, and stay casual, and ALERT, is another red flag.

Pay attention as you move forward.
