The daughter is 22yr and in the past two years that I have been seeing her father she has not made me feel welcome. Of course understanding her own personal situation I can understand certain actions she does as I am taking her daddy's attention away - how odd they seem to me. But, I can not understand when certain actions to me seem to cross the line - such as leaving her bra and panty's in her fathers room, asking her dad to zip her dress up, removing her bra for a massage, neatly folding delicate clothing items (bra, slinky top) on top of her father's guitar. Etc etc.. This I believe is odd.
If there is anyone that can add or comment on this I be interested for views.

Has there been a past with them or is this the first signs? Also is this her real father or a step father?

Do you think the daughter is playing for attention or do you think she is trying to compete with you as a lover? The possibility that she and her father have less of a nudity taboo than you do also exists.

What is her father's reaction to this behavior ? And at 22 what is the reason she is still living at home? It appears she is competing for his attention. Whether it is sexual or not, and the items of clothing really doesn't indicate that, you have a choice to make. Either you get to the bottom of this problem that is really not yours, or just forget about this relationship which may get too much for you to handle. I would not even want to know. It isn't like she is a child.

What has the father said, when you asked him about it.

Do you also live in the home?

I would be inclined, when I found her underwear on his guitar, to say, during dinner, "Oh, somehow your underwear ended up on your dad's guitar, so I put it on your dresser for you."

You need to see how HE responds. If he lets it be known that her sexually charged behavior, for whatever reason- to get at you most likely- is okay by him, then you know what you're in for.

After two years, I would consider just how far this daughter of his, is going to go. You need a good sit down with him, and explain what you have said here, and ask him what he is willing, or unwilling, to do to make you more comfortable in his home.

I'd say two years with him qualifies you to ask some simple questions. You could very well be fighting a losing battle, and investing more of your life with this man and his daughter, is a waste of time.

How do you not ask questions after two years when you have concerns?
