My boyfriend isn't as affectionate as he used to be?

Since you guys have been together for a while he is really comfprtable with you. I think guys do that stuff in the beggining because they know how much we love the attention and to show off a bit:). It doesnt mean he loves you anyless. If you miss the affection like before at school just tell him how you feel or take matters into your own hands and give him a big ole hug or kiss when he would least expect it :) good luck hun
