Right time for another lesson of Guys 101.
First question do you trust him? If you do, then you have nothing to worry about.
Second issue that of the wench herself. From what you have provided as information from a single view point in a vacuum, we can only assume she is jealous. But the question is did she hold his hand in front of you? Or did you just hear about it and more importantly if you heard about it do trust the source?
Lastly he stopped talking to her after you got upset. You know what that means? He places you of more importance than that of the other girl. He broke it off because you were not happy.
In the case of multiple guys at his house, he wants to keep his conversation with you private. Considering what guys say about girls in an all guy house, trust me he does it because he values your relationship.
And lastly and most importantly insecurity and clinginess are great things that break up a relationship.
In your specific case you tell the guy sure why don’t we go together. I haven’t seen her in ages as well and would like to see her.
Plus you have told him you think she has the hots for him right? That alone is enough to put him on the backfoot if you are there.
Thats pretty interesting perspective.
But i dont get one thing, if the girl who can speak to your mother or anyone in your home at any time, has no value to you ? Is that what you are saying?
