what would you do?

okay girls i know i might sound crazy but just listen to me. So me and my bf have been going out for a couple months and i found out he had been on plenty of fish. He told me deleted it then we got into a big fight and found out he was back on it. Granted ik he has trust issues as well because his ex wife left him plenty of times i gave him another chance. Well i found his pof account and decided to create a fake account to see if he would answer and if he is still on. Well he answered and used the same pick up line he used on me when we first met. So then we start talking on pof and i ask him what he's looking for he said just trying to meet new people and see where things go then asked about me and i said i was looking for a fwb or a hookup maybe more down the line he said he liked the idea idk what to do
