What do you think of me giving my girlfriend a month with her ex?
Really? What caused you to let your own girlfriend get with her ex for a month?
Because I love her and I love my friends and I want her and her ex boyfriend to be happy together.
Even if you care about your girlfriend's happiness, I don't think letting her be with another guy is wise. you shouldn't do things that are going to hurt your relationship. You should spend time with her yourself instead.
Give me a break. They won't be doing anything. They will just talk and be together.
It sounds like at the end of the day you've approved of this, so I won't touch on it anymore. What I will say is that most healthy relationships don't have an ex-boyfriend who is allowed to be with his ex-girlfriend for a month while her current boyfriend allows it-- it seems unhealthy and harmful.
