A boat ride around the local lake does not exactly sound like your typical harmless outing between a man and a woman. It would be interesting to know what your husband’s explanation was as to why he was alone on a boat excursion with his hot female boss and her 2 year old child. If it wasn’t business related then it’s impossible to justify it as harmless time spent between friends. This is not the usual way friends pass time; and any argument that it was business related should be met with the obvious questions of why it was just the two of them, why her child was present at the business meeting, and why the meeting was conducted while circling a boat on a lake with her in a bikini.
It’s not a matter of you being an insecure person if you feel threatened by your husband’s apparent fascination with his boss. When he comes home and talks about her, how beautiful she is, how everyone at the bar is always hitting on her, he is elevating her and in the process deprecating you whether his intentions are to make you feel smaller or not. It’s not that you don’t know there are many women in the world younger and more beautiful than you are; but you don’t spend every day of your life thinking about it and making yourself feel older and uglier with each thought. Your husband coming home singing the praises of this woman will naturally make you more conscious of everything that you are not, unless you happen to be a supremely confident woman who never feels threatened or is never made self conscious by observing or hearing about the beauty of other women. Most of us are not that secure.
The security/insecurity argument is not just a matter of being vain and not being able to deal with knowing someone is younger and more beautiful than you. It’s also about being secure in your relationship; and in both aspects your husband’s actions directly affect your ability to feel secure. It’s clueless and insensitive to think its okay to come home and constantly talk about your hot young boss. Then to take the woman on a boat ride and keep it secret; then when your wife finds out about it dismiss her concerns as being paranoid, insecure and ridiculous, that’s not a husband who is looking to protect his wife and see to it that she never has doubt of his love and of his commitment to her. If your husband is having an affair or desiring to have an affair, it unfortunately does not sound as if you are going to be factored into the equation until he either needs a divorce or your forgiveness. A boat ride is a pretty determined move. They don’t take us on boat rides unless they are seriously trying to impress, and they don’t try that hard to impress unless they want it really badly or have just started getting it and are still in the throes of all the physical excitement. I know that’s not what you want to hear and really, it could all be innocent; but then, why didn’t he invite you along or at least tell you he was going to take her and her kid for a ride on a boat for whatever convoluted reason, or tell you about it after he had done it?
