<human>: So I have an amazing boyfriend, let's call him Jack, he's incredibly sweet and kind and romantic and I could go on and on about all the ways he has been amazing for me. He's my bestfriend as well as my boyfriend.

We've been together 2.5 years now and it's my first proper relationship. He always says how I am the one and how he wants to marry me someday. However I'm just not ready for the first person I'm with to be my 'forever', and recently I've been having feelings for another guy (though it's just a dumb crush) and have been thinking of other guys when Jack and I are having sex.

On the otherhand Jack is fantastic! I'm worried I'm throwing away a fantastic relationship just to end up with heartbreak and regret down the road; but then I also worry that if I dont take action now it could be another 3 years and me walking away when it's even harder! I thought about asking for a break but I know he would just see it as a breakup or me looking for an opportunity to cheat or something.

I just am really confused what to do, whether these feeling are temporary (had them for past 2 months on and off) and if anyone dealt with scenario like this before.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: I have a great bf, 1st relationship, he sees me as the one but I dont know if I'm ready to commit forever to a guy I had 1st relationship with. Unsure how to proceed.
