Alright. Agree to spend time with him. get close with him. Do things together. When he asks you out, accept. Use it to get closer to him. Make sure you stay dating for a while. Get to know him as well as you can. If it looks like you won't work out, wait until the opportunity presents itself. Preferrably one that doesn't make him sad.
If I don't know shit that's because I don't know shit
