HELP😬

I have been with my boyfriend for 11 months now and during the first few months of the relationship we were so happy together and I felt so in love but now I feel like it's just boring and I am not in love anymore I have been I met someone last year on holiday (before I met my boyfriend) and we kissed and I was so happy with him however we couldn't be together because of the distance however I am going back on holiday to see him in a few days. I don't know what to do I am so attached to my boyfriend and I can't let go but I know that I don't feel the same love for him as I did the guy I met on holiday. What do I do?!
