You know, I was thinking before that maybe you should send a text. It could be more casual than an email. Just a hi, just wondering how you are doing text. Men don't read as much into communication generally as us women do so he probably wouldn't see that as unusual. I think you want to make it seem like you haven't really thought about it or made an effort and asking him to check his email may put him off.
God, I agonise over everything as you know! So I understand how you are feeling. It is so hard when you are doing these things 'blind' as it were.
Hope you had a good day Jx P.S - I'm with OD, a halter neck is the most flattering swimsuit for ladies with boobs, also pretty good support too :-) I have one pretty similar to the link OD sent. Although mine plunges a bit more - you got to make the most of these things ;-)
