Pretty sure this topic has been covered before but I just wanted to add my two cents to it since I usually attract typical nice guys. Its probably because I'm generally dating down when it comes to looks. I know I sound like an asshole and I'm obviously not a model either but it's true. I like certain type of guy it seems like that's not the type that's very attractive to other women. Which is probably why they do these two things that always turn me away from them:
1. They put you on a pedestrial
Everyone likes getting compliments right? Well only to a certain extend. If you overdue it it can quickly become a turn off. I don't want to be put on a pedestrial. I'm equal to my partner and I don't want him to think otherwise. Besides, it get's boring over time. You'll sound like a broken record. And they'll loose their meaning if you throw them around all the time. I'd rather have a few compliments here and there than getting bombarded with them all the time.
2. They go from 0 to 100
This is something that bothers me the most. They often want to skip the dating part altogether and jump to being a couple or better yet married with a couple of kids. At least that's how it's been in my experience. I've had guys asking me to be their girlfriend before we even met. This is just putting pressure on me. I liked you and enjoyed texting with you so let's go on a date and see how it works out.
But I can't really enjoy our time together if I know you can't handle it not working out. Not everyone is compatible. But I often had my dating experience with a guy ruined because I knew he would not handle me rejecting him well cause in his mind we are basically already married. It makes me want to end things early because then it won't be so hard on you.
