Search Results: when should i contact my ex

So my best friend is literally the sweetest girl who has been dumped on a lot by guys and tbh I think it’s ruined her. She hates men like really hates them and it’s so sad because she once believed in true love. There was this one guy who she dated years ago which ended very badly. There relationship was really intense and chaotic. With him showing all there private messages to his friends at the time he didn’t know that my friend had been attacked a year before they met by a male friend which resulted in her having miscarriage.

After he showed all those intimate messages she more or less had a nervous breakdown and was on the brink of suicide. Years have gone by and my friend has done amazing with getting a degree and building her career etc

However about a month ago the ex who had shared all there messages decided to get back in contact with my friend. At first she told him that she could never be friends with him but now they have been texting. And she has me worried because it’s like she has gone in reverse. She said he will fall in love with her and she will ruin him in everyway possible for how badly he treated her. Him coming back into her life after 6 years has triggered her and I don’t know what to do?

So I've been with my boyfriend for 2 years now
We stay at each others places
He stays at mine
I stay at his

Yesterday, he slept over
He was in the shower and his phone was on the bed
His phone pinged
And I thought it might be his family contacting him.. but it was a message from his ex fling
Saying
"What you doing babe?"

I was FURIOUS!
I confronted him about it and he denied that theyre talking and she just messaged out of no where

So he unlocked his phone and showed me the message
And it was only 1 message from her
No replies from him

I dont know what to believe

Why would a woman out of nowhere just text her ex fling?

The girl is the 2nd picture
she's unattractive

Why would he cheat ON me with her?
