How do I trust my future girlfriend/wife to be honest with me?

One of the main things I want in life other than achieving my goals is to be with an honest straight woman who loves me just as much as I love her. But I'm losing hope and trust and I already have trust issues.

Recently I was on reddit and had a dm conversation with this woman who claimed to be a conservative/traditional and an ex-feminist. I was not pursing a relationship with this woman or anything and I'm not a fan of online dating. I just had this one insecurity and wanted to get her thoughts on it since it seemed like we shared similar views.

She reassured me and we talked about a variety of different topics including political views and religious views. It seemed like we shared a lot of similar views. One of the things she said was that she didn't like how a lot of women are immodest and wear things like crop tops and shorts. I personally don't really care what a woman wears unless she was my significant other and was wearing something too revealing or provocative. But I found it nice that it seemed like she was more old school and traditional. Not even a day later I see in her comment history that she was complimenting a woman on a post of her wearing shorts and a crop top and saying how nice she looks in it. I dmed her and I simply respectfully asked why she was contradicting herself and instead of responding she just blocked me and set her post and comment history to private (Everyone's including mine is set to public by default on reddit).

This is just a more recent example but I've seen so many women online who lie and/or contradict themselves and it's making me lose trust. Even in real life I've met some women who present themselves a certain way but when you get to know them they aren't who they appeared to be.
