Should I be happy I left him?

Yes, you did the right thing. You don't have to put up with his b.s. If he is perfect because I haven't seen anybody perfect in my life. Who the hell is he to judge you? Don't worry about been lonely. Most of the mistake I have done with guys is because I feel lonely and we ended with two problem, being lonely anyway and taking crap from creepy. When you take a lot b.s. from guys, they don't respect you and they start treating you like crap. Now, the thing to do is don't text him any more, act busy if he call. Go out with your friends, get yourself pretty, get a new look. This type of people boyfriend/girlfriend tend to get worse, he is not going to get any better. Let him know what loneliness mean and the girl he lost. If he there with no family that's his problem. He didn't appreciate you. Be a strong girl and proud of yourself. We never should let people, boyfriend treat us like crap. Believe me I learn this the hard way. If I had to go back in time I would never had taken so many crap just because I feel lonely. Don't confuse loneliness with love. Congratulation, I know you will find someone who will appreciate, respect and love you. It take time be patience. May God bless you, he is looking at you kido.
