My boyfriend and I

I am really sad I met my boyfriend 5 months ago today and fell in love. texting talking up a storm. but this last month he just literally hardly texts me and calls me. one day I cried myself to sleep. we have so much in common. I even saw his family on thanksgiving weekend. I don't know what to do he when I call him he doesn't anwser my calls But when he calls I anwser so I can talk to him. also when he sets a time for a date night out example 2pm he will have an excuse saying I am running late can I pick you up at 4pm this just recently it's been happening in December. What do I do I love him but I hate being hurt by the person I love
