Going thru bf sc convos

So I rarely go through my bf Snapchat and today I thought why not? So one of his good friends I went through their convo and I guess they fucked 7 years ago. My bf told me he didn’t remember any of the girls he fucked or the memories but in his message which they wrote each other on sep 24, 2017, he told her she was a “great fucc.” We had gotten together sep 9, 2017. He also said she had “the wettest and tightest pussy he’s ever had.” Remind you they fucked 7 years ago before me and him. And today’s his birthday and she wished him a happy birthday and they exchanged “I love you,” but they hardly talk. So idk I just wanted to vent because now I wanna know who are you friends with that you’ve fucked? I’m not mad I’m just like wondering, questioning just a whole lot of questioning really .
