@frankiefirstyear if you like someone, nerves are to be expected and the chances are he's feeling similar too. The more I like someone, the more nervous I get! But it's an exciting nervousness, not like doing my driving test nerves. Try to enjoy the nerves and embrace the excitement and anticipation!
But try not to worry about it too much - for me the most nerve-wracking bit is the first kiss, which you seem to have got out the way already. Just enjoy his company, and try to distract yourself so you're not spending the day working yourself up about it. And enjoy it - even if it's all a bit nervous and fumbley :)
@WingingItAtLife You're not alone in only being available every other weekend, and you've made that clear from the start so he knows the score.
Personally, I've dated two women with kids (I don't have any), and it's not ideal I have to admit, but life isn't perfect. If I met someone I really liked, it wouldn't stop me seeing them - I like my own time anyway, so I don't mind not seeing someone 24/7. You can do other things like video dates when the kids are in bed, and good old fashioned phone calls.
The first relationship was complicated by the fact she worked shifts and weekends sometimes, so free time was even harder to find. The second one did a lot of other things in her spare time, so we only spent one evening and half a weekend day together the couple of times we saw each other. We both realised that wasn't enough, so we decided to call it a day.
