Hope you guys don't mind me muscling in on your thread with a massive rambling post - I've just started dating for the first time and feeling pretty confused about a new guy.
To give the brief history - we had sex on the first date (instigated by me, oops) after spending about 10 hours together chatting in the pub. Since then, we've had a couple more dates 1x per week (just getting dinner) without any more that a little kiss. Then over the weekend we went out again for a long date, had sex again, and he stayed at mine till late afternoon. Texted afterwards saying had lots of fun, looked forward to seeing me again, followed by bit of mundane chit chat for the rest of the day.
He seems like a lovely guy - straightforward, affectionate, considerate, asking about my family and friends, politics, job etc. and remembering details from previous conversations. Very complimentary too 
He's not texted me in a day and a half since the last time we met and I'm worried that he's not actually interested in me after reading dating advice endlessly since my stupid feelings went all crazy on me. The pattern is that he never ignores texts, but takes a while to reinstigate once a convo draws to a close. This also happened the last times we met, where he didn't text for 2-3 days then got in touch the night before the date to see if I was still OK to meet.
His job is extremely busy, usually 12+ hours a day, and genuinely busier at the moment due to what's going on in the world. Also not British, if that makes any difference.
I wanted to be chilled and take things slowly, but I feel like a teenager again. Am I doing the right thing by just waiting for him to get in touch?
