Conflicted if i should end things or not.

Hi everyone.

So I've been dating my boyfriend for almost 3 years now, we were eachothers first partners.

We’ve had a very happy relationship but for the past few months I’ve been noticing that i dont really wanna see him anymore, don't wanna have sleepovers, don't want to spend as much time with him and when we do spend time together i often get bored and sometimes even wanna go home. I have also not been enjoying our sex either, and for the past few months i have not been in the mood to do it anymore which gets him a bit frustrated.

He has such an immense love for me, and he has even thought of getting an engagement soon but for me, i feel like i am not returning the same amount of love back.

i still often have thoughts on how it would be to be with other men and experience different things. I also often fantasize of being with a man that has quality’s i like which my boyfriend does not have. In fact i have even started to flirt more often with men around me then i have when we were at the peak of our relationship.

Overall i am just very conflicted because i know i have lost a lot of feelings towards him but at the same time i don't know if i have the strength to break up with him.

I just feel like if i was really in love with him, i would do anything and everything for him… but the thing is that i still love him and he is incredibly special to me but Im not sure what to do.

Any help would be appreciated.

Thank you for reading this :)
