Re: Been gaming this one for a year
This one gets sticky, she obviously has attraction to you, but she did sleep with you when she had a boyfriend. This is not good for the trust aspect what is to say if you land her she won't do the same. However I am not saying don't do it. If you honestly like her go get her but keep your eyes open, but don't be jealous or needy.
What her friends are doing is just classic being over protective, they don't know you so they assume lower value. You have to eventually demonstrate your high value but that can be done whilst you two are dating exclusively if need be. The only caveat to that is if you cannot land her without her friends' approval, but in this instance I think she does a lot of things without the approval of her friends
The questions above especially the one of her worried that you will get bored with her is one she should ask herself, obviously she got bored of the last guy. But don't bluntly ask her that a good reply would be I will put in the effort if you are willing to put in the effort to keep it interesting too. Explain that you like to have fun and want to include her in your life so you can have adventures together.
That is my two cents
