Should I be worried ?!

So me and my bf have been together for a month but I’ve literally fallen head over heals, he’s my first and I’m his, in the beginning we were all lovey dovey and when we are together just me and him it’s great but he’s been away skiing for a couple weeks, he barely texts me but i know he’s texting others and sending streaks whilst ignoring my texts and his texts always seem distant. He also told me he was off to bed the other night and 10 minutes later sends me a dick pick as if it’s not meant for me he swears it was but I just worry, thoughts?
