Anyone here can tell me if I am silly in this situation?

I fell in love with a guy a month ago and we met and had a week after that. I paid everything and went out of my way to see him. I lied to my parents that I was on a long term training every weekend in the future. I neverd lied to my parents but I really love him. But I found he has pasts that he is dealing with. He still has contacts with his ex who dumped him and made him very upset even four months ped, he is still talking with him. Everytime I called because I am afraid he can't afford the phone bill even I know he made hundreds of calls to his ex before and they still contact. What made me even more upset is that I found he spent 700 bucks on a person that has VD after we met and he never told me about that. I found everything this time when I was stalking him. I feel I am so silly. dont you think?
