How will I check if there really is something wrong with me?
My boyfriend says I'm nuts. I need to get help because I get an overwhelming feeling that he is cheating on me.  Whenever I try to talk with him about it, he always turns it around on me by telling me what I'm doing wrong. I know that accusing him does not help.  When his whole demeanor shifts towards me, I can't help but think that something is wrong.  Am I wrong for feeling this way?  I try to talk with him to make it better.  I let him know when I am feeling down. But I am not confident in these things. 
Two weeks ago a girl texted his phone 3 times trying to hook up with him.  He texted her back with "Sorry, I've been working.  I just read your message." The girl was trying to get him to call her at a time when he was at home with me.  He texted her back with "Don't text me anymore."  I don't feel like I am way out of the line. But I can't talk with him if all that he will say is that I'm crazy and I need help.  What should I do?  How will I go about checking if there really is something wrong with me?
