Not sure how to procede or let it sit for a lil while?

background: met this girl when i was out in the city. had sex on the second date, after that pretty much just sex/hanging out dates at my place. I went to travel a bit, so we hadn't seen each other for about 3-4 weeks. once i was back, i felt it was a bit more difficult to meet up with her again, eventually we just met up for dinner (last sunday). -the vibe was a bit off at the dinner, she was a bit more distant, which in return felt also weird to me. nevertheless, we did a lil walk around the nearby park and just made out a lil before saying goodbye. -on my way back home i received a text from her where she apologized for her behaviour and being so distant. she didnt feel liked it matched with us that evening, that's why it became a bit uncomfortable to her (so I probably fucked up during the dinner date and got stuck in my head too much). since then we just texted a bit back and forth but i havent pushed a for any date. should i just let it chill for a while or trying to set up another date rather sooner than later?
