HELP. Is this deliberate?

So I haven't heard from the narc. I told him I didn't want to contact him after we broke up around 2.5 months ago. He seemed to respect this very easily. He swore on his life he was distraught and had no intention of touching another woman for a LONG time. I mysteriously found a new box of condoms in his drawer a few days later. He gas lighted me into believing we bought them together which I later realised was bullshit.

It's been 2.5 months since our 5 year relationship ended. We were engaged to be married and I 'thought' deeply in love. Hahaha! I have an app on my iPad called drop box which he had on there for work when we were together. I happened to open it tonight to check out what it was and low and behold there's 100s of photos of him with 2 new girls kissing them and taking romantic selfies. The folder is called 'amore' ('love' in Italian) and has photos of him with one girl he's clearly met a few weeks to a month after me. MY photo folder used to be called the same thing. There's also a 'private' folder within it but the most private is him kissing her without a shirt and her sleeping.

Do you think this is deliberate or coincidental? Is there a way he'd be able to tell I can use Dropbox from my device or was this a screw up from him? He's blocked and deleted all my family from fb so it looks like he WANTS to hide his personal life.

I'm actually not sad which I'm so happy about. I'm a bit in shock. Mainly at the fact at how I was so often criticised because I wasn't stylish or feminine enough. We'd argue endlessly about me not wearing high heels or putting in an effort which wasn't true. This new girl is an unkempt hippie in flats. Wtf.

What do you think I should do? I'm going with nothing. Or should I tell him his stuff is visible to me? I don't get how drop box really works. Do you think this is intentional guys? :)
