For the fact that she told you all these means she is faithful and truly love you. Some will do all these secretly without telling you and look for an excuse to break up with you when they feel it's time to move on. Her telling you that the guy needs a yes might not necessary mean she's considering the option, and might not also mean she's pressuring you to marry her. It might just be her way of telling you that she wants an assurance that she will be the one you will marry when you are ready to settle down.

If you love the lady, you can just give her the assurance, but not directly telling her that you will marry her.

The topic should have been 'All the girls I have been with are gold diggers" Op take note. in case of next time. Do not generalize.

bro forget long story. It's obvious you really don't like your neighbour. The one you like is playing mind games with you. You asked her out the first time, she just laughed. The second time, she said she needed time, and the third time, she already has a boyfriend. Just ignore both of them, or continue being just friends with them. When you return, tell the friend that you already have a girlfriend who lives in Lagos, and end it there.
