Help me find it please?

looking for a shoujo manga about a girl who was reincarnated multiple times, and in each of her lives, (i think there were 4 including her current one?) she dated the hero, and they ended up leaving, or cheating on her. So in her current life she's dating the hero again (i remember him having like shoulder length hair) and she's scared he's gonna leave her so when he goes off to fight, she basically runs away? not sure if it was finished but i remember basically they got together again and he didn't abandon her when he got back

tysm!
