I guess people were taken aback by this thread, as you don't just decide to be bisexual or les due to having bad experiences with sleazy, selfish immature lads, your orientation is something you should be aware of regardless of any actual relationship experience. As for the other comments, maybe having a proper conversation and setting your boundaries would bring more closure than a text? It's lockdown so he shouldn't be at your house anyway. You are in a fortunate position to not be living with this man or financially tied to each other, so have that conversation and move on with your life, you are so young, have fun being single and be content with yourself, it can take time to work things out in regards to orientation, good luck, all that matters really is that you aren't put in a position where you are undervalued be it with men or women.
