I'm just thinking at 139, what on earth are you worried about!?!? You are probably pretty hot yourself!
I don't blame you for worrying. I would too! I used to worry every time my husband went away on business, especially when he went to Florida during spring break... or any time for that matter! Although I miss the "free time", I don't miss the business trips at all! I feel much better about myself at this weight and with this body, so I wonder if I'd worry less if he traveled now.
I tend to be a little bit on the jealous side, and I don't think it's foolish or necessarily bad to feel that way. I think it's what you do with your worry that's most important. If the green-eyed monster comes out, that's bad. It's one thing to secretly worry, and it's one thing to nudge for a little reassurance from your man. It's another thing entirely to go all crazy on him over something that might not even be a problem! KWIM?
I don't think you're foolish. Just normal.
