4. You won't commit already. Now, if you aren't in a full-on relationship with them and you have been dating her for months, your inability to commit will make her wonder if she will ever have you as her one and only. If you haven't committed to her after a few months—or even six months—then maybe you should look at yourself and see why that is. And just maybe you need to move on if you are hesitant in thinking she is the one.
5. You push her around! It's nice for a woman to feel safe with her partner, but if you are telling her what she can and cannot do, this is going overboard and not good for the relationship. A relationship should be 50/50 (as opposed to having one person in control and the other just tip-toeing through the relationship).
These are just a few things that women have issues with when dating. If you avoid the things mentioned then you and your partner should be harmonious and loving towards each other.
