Does she want to get back togther?

basically here is the situation, a girl breaksup with a guy coz she felt that they werent seing each other enough or spending enough time togther. she says she had been cry about it almost everyday. and bin tellin him but he had kno idea how bad it was affecting her. So she breaksup with him and he didnt really understand the whole situation. they go to the same church so see each other at the service when she is in. now its bin ova six months since they actually talked to each othr face to face. the girl wud always b angry when she cs the guy and the guy not knowing about wats actually happenin decides to confront her. they talk and he finds out that she is still upset about hw the relationship ended, and wants an apology from him for makin her cry and stuff, he also understands that he could have done things differentl . So do you guys recon she wants him back? and should he write a apology?
