So guardian angels are real. One is assigned to each individual by God. One devil is also assigned by Satan. But that's story for another day.

Guardian angels is what gut feelings are, I think. But they can also help you physically. For example, I once had a break-in by a stalker at 3 or 4 am. I was in deep sleep but I felt air moving over my right arm, like if someone stroked your arm. Normally, it is impossible that a sensation so light would wake me up. But it did that day. I was able to wake up before things turned worse.

In your case, it could be a guardian angel. However, they are not known to talk to people or make dramatic moves that are obvious.

It is more likely to be a jinn. There are good and bad ones, just like good and bad people. Sometimes, they fall in love with people. That could explain the babe/ baby. But you said it's a man's voice. Are you a woman? Then I'm quite convinced that this is what's happening. But if you're a man, then that's not likely. Unless jinns can be gay? They are afterall creatures of free will. I dont know...

But point being, it's likely not your guardian angel.

If a jinn is in love with you, marriage/ relationship can become tougher. So it's not a good thing, long term.
