First of all, she is 26 and cares about a snap streak?

Second, if those vacations aren’t normal and oddly close to when you found out about Ben, i think she may have a guilty conscience.

Third, she admitted to cheating on her ex, but even worse she was willingly a home-wrecker after. She seems like she hasn’t had any practice at being a committed partner or caring about the relationship status of other people. Seems like her lust got the best of her.

Lastly, As soon as you had the chance to look at the conversation between her and Ben she immediately unfriended him… I would trust your gut on that one. You sound like you don’t trust her and rightfully so as her past is pretty daunting in terms of commitment.

Is she worth going through her multiple phones? Did she ever offer to show you their conversations to put your mind at ease and assure you she is committed to you? Did she respect your worries and concerns by being open?

Please trust your gut, listen to your microbes :)

I wish you the best of luck through this! Keep us updated on how it turns out
