Is Boyfriend Cheating?

DON'T ever doubt yourself, trust your gut feeling because more then likely its right on target!! He seems to be too nonchalant about what you have confronted him with, and its quite odd he CANT remember what his conversations consisted of, and he DOESN'T know why he didn't tell you he was hanging out with this girl, im sorry but this all spells a lot of trouble for you, get out now while you can, don't allow yourself to be treated like this!! You love and respect yourself more then to EVER allow this guy or anyone else to treat you with such disrespect, YOUR NOT A DOOR MAT, you matter and you deserve better!! Be strong and do what you need to do, but don't let him treat you this way, draw the line and set your boundaries and stick with it, if you don't respect yourself no one else will!! Remember a guy will only go as far as a woman allows him to!! Good luck to you and i wish you the best!!
