<human>: Can you succinctly summarize the text in 1-3 sentences?

My best friend and roommate (M 21) and I (F 21) have known each other for four years now. I have had a crush on him for nearly the same amount of time. About three months ago he admitted that he also has feelings for me other than friendship but they are new and he doesn't want to rush into anything. He says his past relationships were started on an impulse and that's why they did not last. 

My question is this: should I ask him out on a date to see if we could make what we have work or just leave it alone?
<bot>: Four year friendship. Stronger feelings are there but he is skittish because of past relationships. Should I ask him out on a trial date?
