Could hydroxycut cause this?

Okie my boyfriend of 9 mths has recently (past 2mths) has been very pushy with me, he has his own house and I'm still with parents cuz I'm 20 and he's 23. So I go to his house till 10pm every night we play games (wink) flirt make out and watch movies and cuddle. Well recently he's been kicking me out earlier then normal we don't cuddle anymore and all the romance seems to be dis appearing. He has had one incident 4 years ago where he overdosed on this dieting pill. He is currently using the Pill again to lose weight for a wedding in a few months. He has had a nose bleed and is constantly complains about his stomach but he also works as a delivery person so he does alotta fast-food. He has become more snappy at me lately he has headaches and he's just not himself anymore. I'm wondering if it's the diet Pills?
