'She won't send me risque pictures on Snapchat'

Is it wrong for me to ask my girlfriend to send me pictures of herself on Snapchat? I send her risqué pictures all the time, but she is wary of doing the same thing. Doesn't she trust me?
I suppose it's about trusting technology that's the problem here. If she's not comfortable putting up pictures on an app, we all know why she should be wary, considering the sheer amount of data leaked online every other month. If you're comfortable sending her risqué photographs, that's your prerogative. I don't see why she should be compelled to feel as comfortable with the idea though. It's her body and if she doesn't want to risk anyone seeing those pictures, you should learn to respect her decision. If she trusts you enough to be in a relationship with you, why isn't that enough?

I wanted to go on holiday with friends to Bangkok, but my girlfriend threatened to end our relationship if I went. She said I would be unfaithful to her on the trip, which makes no sense because I have never done or said anything that could make her doubt my faithfulness to her. This has blown up into a huge issue now, because my friends think she's being unreasonable. I think she's being unnecessarily suspicious, which is sad because it means she doesn't trust me enough. I have told her that we should end the relationship anyway because, without trust, there is no future for us. Am I being hasty?
I don't know about hasty, but I agree with you about the importance of trust. If you have given her no reason to not trust you, this really is a problem. I suggest you both think about why you chose to get into this relationship though, what you liked about each other and why you suddenly have trust issues, before taking the next step. If it's something that can be fixed with open and honest communication, why not try that first?
