Robert Pattinson & FKA Twigs Engagement 'Struggle' - Kristen Stewart's Ex 'In Love,' New Girlfriend Hesitant Amid Marriage & Pregnancy Buzz, Break-Up Soon?

Things are moving pretty fast in regards to Robert Pattinson's blossoming romance with LP1 songstress, FKA Twigs. But should the 28-year-old British heartthrob take a step back and just enjoy the moment with his new English muse?

Rumors initially suggested that R-Patz already "secretly" proposed to the 26-year-old aspiring singer. An alleged source for the sometimes shady gossip webloid HollywoodLife.com recently revealed:

"Don't be surprised if you see an engagement ring on Tahliah this holiday season or at least sometime in the very near future... She is everything and more that Rob has ever dreamed of. They have crazy sexual energy plus they are like best friends. He feels like she brings out the best in him. That she makes him a better person and a more daring, fearless artist."

But now it looks like such engagement buzz is indeed NOT true. Twigs wants to slow down and take the time to actually enjoy this growing romance! Still, Pattinson's love proves extremely strong (even more so than when he dated former "Twilight" sweetheart, Kristen Stewart). Another HollywoodLife insider explains:

"His relationship with Twigs is going extremely well - he has been telling friends that he loves her."

So what's the hold-up from actually making things more "official?"

"She doesn't want it - they are enjoying each other without needing anything more at this time. They are young, in love, having fun but nothing more, don't anticipate wedding invitations," the snitch continues. "She likes Rob a lot but she is not in the marrying mode or mood right now... She doesn't think it should get to that level right now." 

That makes sense, right? No tensions, but no pressure, either!

Still, wedding bells are still likely sometime in the future, considering "There's absolutely no question that Rob is in this for the long run."

Sorry, Robsten fans - looks like this relationship is pretty solid, so far!

And despite crazy baby bump hype, Twigs is NOT pregnant. They've only been together for a few months!
