Organize your time. There's no need to put much concern on your love, you need to learn that texting people 24/7 is not love. Love is not about having butterflies in your stomach, it's about staying together even when it's hard. True love will always have your back. So keep going, reorganize your time tell him you're busy but keep consistency.
He needs to learn that he has other goals, he has hobbies, free time, friends. Anything that makes his life grow. True man has to build his value, women are born with it already. When he focuses on his goals and checks upon you when he has time, that's what should be healthier.
There is no need to stress so much about love, your overthinking and loving too much can lead to deep wounds if broken one day, but you are a good woman who sees the pain in him.
Focus on your life too, both if you will shine bright if you keep focusing on yourself too.
