Men are not complicated. He's not investing in
you because you're not worth it to him. He's
not chasing you because he doesn't want you,
he's still entertaining you because you let him.
He's not giving you what you want because
he's not afraid to lose you. Stop making
excuses

To expand on this further, google the term breadcrumbing because this is what these toxic men do BECAUSE YOU LET THEM.
As women many of us already deal with enough through out life with self-esteem issues and etc.
Men only do any of this because YOU ALLOW THEM TO.
What you allow is how they will behave and continue to behave towards you.
We teach people how to treat us, so if you love yourself enough to know what you will or won't allow then men like this will never be an issue.
I always got confused on when someone says I allow said person to do the things they do. And found it elusive - esp when I was young and didn’t understand - heck i didn’t even know that I was being breadcrumbed at some point too! Does that mean if I find that someone is not giving me what I want I just cut them off? How do you handle a situation like that and now allow them to do that? Does not allowing mean you still engage with that individual and tell them to stop breadcrumming? I only ask because it seems the only way to not allow someone to do something is to completely cut them off lol
Usually If something like that happens with me I just tell them straight up - “what are you doing or what do you want from me or are we penpals?” Or i just completely fall off the face of the earth.
I guess not allowing someone to do something wasn’t clear on what I should do (I’m not nitpicking on you my friend it’s just that word has been said many times to me before and I just wanted to share my thoughts lol)
Eventually when it does happen I just block the dude. Usually I will say why too so I can hit them in the face with it lol
