HELP!! Please What Are The Signs Your Girlfriend Wants To Break Up?

Good Day Everyone,
I don’t know why I will be calling my girlfriend these days she will not pick or even return the call.

Chatting on WhatsApp these days is even hard. She replies when she wants.

This is someone when I met her she used to always call and text me regularly.

Our love was endless till i lost my job and cant afford to her needs.

I never again send her N20k consistently, etc. She recently different. I need money to grow my company. She agreed when I explained this to her.

Imagine my girlfriend telling me yesterday that I Talk Too Much. She has never used these words to me before.

Please I need advice
