If you knew the truth would you call your BF on it?

How can you be serious about a good strong relationship when he is lying to you!! Ask him outright, after six years you should be able too as it is already stressing you out, and do you really wont to live in a unhappy relationship for the rest of your life together?

i'd call him on it. you said you don't want anything to change but things are already changing. you can't worry about it ending because what if he is cheating on you this weekend, do you still want to be in a relationship where your man isn't commited to you? call him on it. if it ends then you know he's not for you. you deserve someone who will be commited to you and honest with you. don't think about how long you've been together, think of the quality of your relationship. reevaluate how you really feel. make sure he knows that you know he's lying tho. and if he is planning on cheating on you, dump him. he'll have had his chance and he doesn't deserve another. then you go find mr. right (if its not your bf now)... if he's lying and cheating he's not mr. right. he's mr. idiot.

You need to call him on it. Most of the time when they lie about where they are going its to do something they shouldnt be doing in the first place. If you let him get away with it once he will think it is easier the next time and it will just keep going. I know you dont want to be hurt so you better fix it before you get hurt and end up losing him anyway.

Call him on it, see how he reacts and listen to what he says and go from there. If you think that he's cheating realize that you might be right and prepare for the outcome of that. Are you ready for that outcome? If you would still stick around after learning that then I say good luck. If not, I say get out....

If it were me, I'd call him on it. Lying to you in order to spare your feelings is still lying.

You answered your own question - you don't want to end it, so don't call him on it. Just be prepared for more "weekend outings"....

I would call him on it but thats just me. One lie will turn into another and another.

if you have wasted six years all ready just keep quit and waste the rest of your life
