I really want to text him?

I got a very short term job in a restaurant where I met this really nice guy whilst on trial. He was really nice to me and I was looking forward go getting to know him, I only knew him for four days and he was hugging me and gave me a kiss on the cheek and seemed really protective of me when I told him I was cycling home he gave me his number to let him know I got home safe.

But then I lost my job twp days later because I lacked the appropriate experience and I was absolutely distraught. I haven't heard from him since, but I really want to get back in touch, its been almost three months but I go passed regularly, should I wait until we bump into each other or bight the bullet and send him a text?
