My bf says he’s bored of me, and thinks about being in relationships with other women! ?

This is normal behaviour of a guy who hasn't been with a lot of women, but knows he has a shot. I felt this way about my first girlfriend. It's time to move on, because in his mind, he already has.

It's an excuse to blame you he knows you are not boring and just wants to have as much sex and with as many women as he can and has a better chance with other women if he has a girlfriend.

You should leave him. I will take you and we can be happy together.

I would leave. he clearly is thinking about other women and not thinking about how he could improve his relationship with you. I understand he hasnt dated many girls in the past, but you guys are together for 3 years and this is how is he thinking. Maybe have time apart will help him understand. 

He's a shallow ****, leave his trashy ***

Leave him, if he's saying that he aint worth your time

LEAVE him and NEVER return to him.  Once men begin behaving like this - they NEVER change.

You should leave. and you're boyfriend should know a better way to phrase that. i.e I think we're in a rut, and we've gotten comfortable? But his mind goes to I want other women, tell him to date other women and break up. 

My boyfriend and I have been together for 4 years, I was his first too, and I completely understand how YOU feel.  I honestly think if he's honest with his feelings and telling you he is tired, I would leave before things get worse. Not all obviously but it is hard for a lot of young men to only want 1 woman and if he is already thinking about other women you should just save yourself and your feelings. Your young years are the years to start over, and you deserve better than that!

SCREW HIM! Leave straight away, I can't believe you are considering anything else

OK step back and look at the both of you.  He says he's bored? really?  He sounds charming, Let him go... he's playing games now.  You say he's played the field, but come back to you? Are you thinking this is somehow a good thing? Do you think it's flattering? Do you think it's a sign you are 'meant to be'? Or do you think this little boy is an inadequate child who lives in a dream world? I wonder, too, how much respect he has for someone who will sit there and be told he is bored of??? He must think you are desperate.  Let the little boy go.... get some self respect. Saying you 'can understand his curiosity' is tragic... I hope you don't think this makes you look mature and understanding blah blah, because it doesn't.  I really do think you should send junior packing.. but I somehow doubt you will.
