You should read the featured story on my profile-- because there is some issues between you two that need to be identified, if you want to make it work.
Without "The Four Elements", you are guaranteed failure in your relationship. Also, don't take this the wrong way-- but as a rule, humans tend to project what we ourselves are capable of upon those around us-- Liars never take anyone's word, Thieves never leave their stuff unsecured, and CHEATERS DON'T TRUST ANYONE. Unless he has actually cheated on you in the past or cheated on his previous with you, I'm wondering on what basis you keep accusing him...?
Definitely doesn't sound like a healthy relationship. If he's going out with his friends every night, then you aren't in a relationship-- you are just a hook up at his convenience.
no he might not be cheating but u will push him to do it if u don't trust him. Did u cheat on him? I know I alway thinking if my man has cheated do to fact I cheated many times.
may be its because his dad told him to dress better
So you didn't appreciate that he picked you up and he was dressed nicely? You immediately suspect he is cheating? or has he cheated before and now you cannot trust him? Sounds like you have a reason not to trust him.
And did you believe him? Did your heart? Did your head? You cannot make someone feel like cheating if you mention cheating. That is like saying if I mention suicide, then you will kill yourself. A big myth! Have a heart-to-heart conversation. Allay your fears. Hear his words. Make certain he hears your words. Then deal with it. Good luck!
