Dear Thelma: 'I love my BF but long-distance relationships are hard'

Dear Thelma, 

I’ve been with my boyfriend for almost two years. He’s three years younger than me. We met during college when we were classmates. We started as friends since we had a lot in common. We love guitars and the arts. We began to exchange text messages and phone calls. At first I was worried because I'm older. I didn't believe it when he said he loved me. My friends told me it would be difficult to commit to someone serving in the church. But it’s actually harder because I don’t have enough time to be with him as I’m working. He always makes an effort for our relationship, and I know he feels disappointed. But he doesn’t want to upset me and so he says he understands my situation.
