Hi @Chretienite
Thanks for sharing. One hand, I can hear how exciting this must be for the both of you. On the other hand, I can see the difficulty in your situation. Please know that you aren't the only one who has grappled with something like this 
It is possible that a casual relationship can have the same risks as a long-term relationship. This is a really difficult choice ahead of you and unfortunately, nobody here can tell you exactly what to do. The whole 'not catching feelings thing' is a game that a lot of people play while 'dating'. If you ask me, it is a hard game to play and there is no way to be sure how it will pan out. It is a risk in itself. If I were you, I would talk to your friend about all of the possible risks and how both of you aim to control that risk. Secondly, what will either if you do if the risk increases or if it begins to have an unwanted impact? That way things are very clear and well thought out. If I were in your position, I would want to think what is the worst thing possible in this scenario? If I could not be comfortable with the potential for that to happen then that would form part of my decision.
If you want to brainstorm some things here, feel free to shout out!
