Its Not Sam
Finding the right words to say when you are on verge of breaking someone’s heart by announcing the breakup is extremely difficult. This person did a failed attempt in trying to soften the blow by shifting the blame from them to something else.
We can imagine the person reading the message wouldn’t have been like ‘oh great at least she is not in love with Sam.’ We are also not very sure if mentioning that she found out only recently that she didn’t love Adam helped him in any way.
