Advice please

I feel unimportant in my relationship. I’m only able to see my boyfriend once a week due to our jobs and the fact that he lives 1 hour away from me. Our text communication throughout the week has decreased to maybe 4 texts a day, yet he is active on his social media. Sometimes I literally feel like I only have a boyfriend on the weekends. He has said that I’m “clingy” when I try and text more. I don’t know what to do.
