Should I be more mad at him or her?

[Anonymous]

My friend and I are close friends with this guy. Him and I are just talking but have potential to be dating soon.
I’m bothered by something that happened recently between us. He went through my friends phone and went through messages between her and I. He saw pictures we sent each other and messages I sent. Pictures I wouldn’t want him to see. She allowed him to go through them.
I found this out because he told me.

You should be mad mostly at YOU. If you sent someone else photos that you didn't want shared then you either should NOT have sent them or you should have sent them and said that they were for your friends eyes only.
I've had ladies sent me naked pictures of them. When they do I look at them (gratefully) but I NEVER show them to ANYONE else (male or female) without asking permission first. Some women who've sent me naked pictures have indicated that they trust me to not just show them to a group of people and to make fun of them but that it's OK if I showed them to my best mate. MOST hoever, expect them to be kept private.
However, if they are not really private pictures in the first place then what is the crime?
If the texts that you two shared were about the guy and you were sharing with your best girlfriend then she had no right to show him then texts.
In any case I think you have a trust problem with your friend and you can be mad at her but there seems to be no cause to be mad at him and, again, the person you should really be mad at is you for trusting someone you perhaps shouldn't have trusted or for not explaining that these were private and not to share them.

Mad at yourself. Don’t send something to anyone you wouldn’t wanna risk being seen by others. Unless your physically seated with your friend, you have no idea who’s around when you’re sending those embarrassing, suggestive, sexy, etc pictures, so it’s better not to send them at all. Lesson learned.
