unsure

ok so I started this relationship with this guy acouple of weeks ago, and at first everything was really good. We talked everyday and he came over 4 times in one week but he works to jobs and now in the last week the communication between us is very minimal if not there... I asked him straight out if he was blowing me off bc it felt like it and he contacted me and told me no... he was just working alot and soon it would be diff but its so hard. I have been blown off so much in the last yr and I thought this one was so diff. we are  so comfortable around each other, he told me tht he should be able to come over this week or weekend even.... I am scared tht I messed up another relationship and dont have a clue how.. I really like this one... I am so stressed out on top of my ex husbands fam trying to get ahold of me to see my kids and as far as I am concerned they are no longer family!!  I have gotten sick twice now in one month and getting behind in school, I almost feel heart broke..  My daughters bday was sunday and that started the events were my current stress is coming from. first her dad called to wish her a happy birthday nice right Wrong!! she ended up in tears bc she wants to see him and I cant let her. He never went thru the courts to see them, then the messages started thru my myspace which I stopped by setting it to private so they cant contact me thru tht any more so hopefully my stress will go down......
