Mother In Law

So my future mother in law is great, to an extent. However it seems as if she isn't wanting to except that he daughter is a woman that is engaged to be married. At times my finance (nicole)s mom knows she's loosing control, and gets over whelming. (like Monster-In-Law, Nicole said that's how her mom is sometimes like that to me) This past weekend, her mom and her went shaping. They had fun looking for flowers, and what not for our house, then started buying me cloths. They started talking about our wedding, and when it was ect. Her mom seemed to for once be on my side of things. They then got on the fact of Nicole living with me, and getting a job in my or near the town I live in. I just don't get her mom. She can be so confusing. For example, wouldn't a mom that knows her daughter has been with a guy for 2 years (last year) and is saying that her insurance isn't going to cover Birth control help her daughter figure things out? Rather then just say "just don't get pregnant"
Nicole was all freaking out, so I found Planned parent hood, and got her a appointment. Her mom then wondered how she got the pills, and why she needed them. Yet her mom told her not to get pregnant. Now after being together for 3 years, her mom asked if I was pleasing her like a woman needs. I mean WOW I just can't keep up. Way back when her mom and I would have conversations about sex, and what not. Not like about her daughter and I, but in general. The night I asked if I could have their daughters hand in marriage, I had to ask both parents(weird but ok) her mom told me that since she was allergic to latex, that nicole probably was, and that condoms are usually latex. But since she was on the pill, that we really didn't have to worry ect. I am just so confused. At times I love her mom, and times I can't stand being around the lady. I mean we are all adults, her daughter is getting married, is living with me. It's just weird. O and this tops the cake, Two Christmases ago, I got her mom baby socks, and said something like " congratulations grandma to be" the look on her face went from being puzzled, to joyful. Can anyone give me any advice? This is the lady that asked me what I thought about her daughters breasts?
