请教，这段话什么意思呢？

Hello,
This is M. I just wanted to apologize for the way things ended between us. I really did care about you and I still think about you all the time. I was trying not to, but I can't help thinking about you. I should have told you that I had a girlfriend, but I didn't because we were broken up when you and I met. I didn't want to drag you in. We ended up kind-of getting back together, which is why I was acting strange.

I am single now. I hope I can see you again one day. How is home? I am sure you family is happy to see you!

Wo zhu ni kai xin,

M
