Can someone help me please!!!!!

I need to get into my bf's email account. On a normal day i don't check his email or any of his private things even though i have had his password but he's been acting so strange lately, and I abandoned the idea of trusting  him especially now that he apparently stole some of my money. And at first i had his password but now he's changed it and I'm really scared . I don't know what to do or what's going on in his life anymore. I suspec that he took the money to buy gifts for another girl but I'm not sure, and I'm really so confused please help me.

please,are you still interested in somebody like that?
