My ex and me still keep in touch and meet up whenever we get a chance as currently he has a new girlfriend. I miss the familiarity of it all even though we dated only a few months and also feel a deep connection to him which makes it easy for me to open up and share my innermost feelings with him. Anyways to cut a long story short, I lost him due to my childish behavior and immaturity but that was a year ago and now I really feel that I have matured somewhat. Sadly its too late now as he has recently begun to see another girl. I really wish I could win him back. I know it sounds selfish but I don't think the girl really loves him as she seems to be treating him like an ATM machine. Please advise. Thank you in advance.
