One thing I will advise with online dating is to not judge too harshly based on petty stuff like spelling or grammar. I only say this because if I had done this I may have passed up the opportunity to meet my DP. From the first email he sent me I could see that grammar wasn't his strong point, but thankfully I was able to see past that as he actually seemed like a lovely guy (we emailed back and forth in the days leading up to meeting with him trying to convince me to meet up, which we did 6 days after he first sent me a 'kiss' on RSVP).
My advice is to try to overlook superficial silly stuff and meet sooner rather than later so that you don't waste your time on people you may not have chemistry with in person. I had every second weekend kid free and my plan was to fill my kid free weekends with dates...then DP sent me a kiss the day after I opened my RSVP account, we met 6 days later and the rest is history! We both shut down our accounts the night we met!
Before I met up with DP I was also emailing back and forth with about 5 other guys, and honestly they were all pretty nice. Four of them were single dads, one was a teacher my age, one was a sweet guy 4 years younger than me (also a single dad). I could've picked any one of them, but DP's personality shone through and in the end he seemed the most keen to meet up straight away and give it a go.
