WE KEEP HITTING EACH OTHER WHILE WALKING TOGETHER?

Does it mean anything if you and a friend of the opposite sex are walking side-by-side together and you find that you're both constantly bumping into one another during the walking? Like me and my guy friend are walking outside together going to a place, and as we're walking and talking, we end up walking so close that our arms or side of the body keeps hitting one another? Now I don't know if it's just me that's walking so close or if it's him, or if it's us both. Personally, I've harbored a crush on this guy for months but have not confessed, don't think I will because I don't want to jeopardize our friendship. Also, we got food together and I paid for him because he didn't have money. Later on he texted me thanking me for the food, I replied with a "you're welcome <3" and he texted back "thanks again <3". So does that mean anything that he gave me a heart back? He also calls me homie, broski, home slice, home skillet, dude, and fam often.
