Does this sound like a good idea?

Does this sound like a good idea?
Ok this girl can't get over her Ex and is going on dates with another guy when we have been going on dates for 6 weeks...

Im taking her on a date this Sunday...After the date I'm thinking about asking her a question..Do you wanna keep going on dates like this or do you just wanna be friends, be honest with yourself and don't worry about my feelings...

if she says yes I wanna keep going on dates them its all good...

If she says No I just wanna be friends, Then I'm gonna act like it didn't faze me and after I drop her off at her house and am driving home..im gonna text her and say.."well it was fun while it lasted, but I can't just be friends..because I like you too much and when you get a boyfriend ill disappear... So I guess I can't be your date for prom anymore either, don't worry about paying me back for the tickets..just take the other guy your dating and have fun. Goodbye.
