The relationship status part meant that it doesn't matter if he's single or not. This quote came from a conversation about me still loving him (even though he's dating someone else now).

If he still loves you for real he wouldn't have gone after another girl. Now he doesn't have any real feelings for you. Just avoid him.

It mean's he won't have feelings for you again. If he's single, he won't think of you. If he's with someone, he won't think of you either. If he's just crushing on someone, he still won't have feelings for you. The "probably" is just thrown in there to throw you off. But trust me, guys try to be dogy af.
