Don't know what to think

Ok so I finally heard from my boyfriend yesterday.... He says that the reason he hasn't called me is because he got a new cell phone and gave his old one to a friend and forgot to put the numbers in his new phone... That I believe because I know how he is.... The only thing that confuses me is what he's doing when he's gone for days and days. I am really starting to fall for him and it scares me a lot. I haven't felt this way about anyone in such a long time. The last time I felt this way was with my jr high sweet heart and that was years ago and this feeling is much more intense. I'm affraid that my jealousy could hurt us in the end, but at the same time he is jealous when it comes to me too. Like my girl Mollie when she comes around.. (This is gonna sound weird.) She always hugs me and grabs my butt... We laugh about it, because I have a bigger butt then she does and she always says she wants it, so she tells everyone that it's hers. When she told my boyfriend that he said nope that's mine.. Mollie's boyfriend does the same thing but he doesn't grab or anything like that. I think he got a little jealous of him too. He just kept on holding me close to him like he wanted to prove to everyone that I am his girl and no one Else's.. Which doesn't bother me any because he is my guy and no one Else's.. The world already knows that... When he kisses me, he takes my breath away. I feel like if he wasn't holding me when he kissed me that I would fall to the ground... I love looking into his eyes, because of the look that I get back from him.... Anyways enough about that. My brother's ex just called and she is pregnant and she had some test done the other day and the doctor just called and said that they are pretty sure that the baby has down syndrome. She has to take more test to be sure though. This sucks, and it's really sad.....
love and peace...
