is my boyfriend too busy for a girlfriend?

okay my boyfriend is saying to me that he really loves me and wants to be with me for as long as possible and i am in love with him too.but im somehow afraid we wont make it forever or as long as possible because i dont see him as often as ide like and he has to work and play football.it makes me sad thinking that he is too busy to have a girlfriend and then i start to put myself down cause he is a hard worker and so amazing that im not good enough for him.i just dont see how he even has time to think about if he truly does love me or not.i dont want his work to interfear with our love. i want to last with him but im scared of this getting in the way.
