A guy and a girl are forever together. Sounds romantic, right? No, it's not. It's the best characters for the most drama and nonsense you could have ever seen, believe me. Nothing can ever stay right, it's boring literally if something stays right forever.
To add some interest to life, god added doubt to your life. That doubt is always fuelled with stuff around you, this article for example. Anyway, girls doubt like everything a guy tells them, even though she will trust him with his life, she will always think that the promises he makes and things he does is something else and something wrong. Her mind cannot think straight ever. Some signs, maybe the behavior, or words or something, will tell a girl things which she isn't supposed to know or assume, but well. Here's a list of reasons to assume that you're not the one, again they may not be true in every case as this is only general. Don't hate us.
When you feel that you two can talk about something and you get really excited about it and start to tell him stuff, but sadly he seems uninterested or really just with a lot of stuff. This really disturbs.
Making love becomes a hit or a miss. You two don't spend the same time in sheets. This can either be really good or be really bad, depends on the person who's thinking about it totally.
You want him to tell the world that you're his girlfriend, but you're in girlfriend in private. In the outside world, with his friends and everything you become one of his friends and have to act like that.
Having some work, having to go somewhere or getting an important call or forgetting and many such reasons are listed when you ask him why he couldn't make up to the last date or something. Maybe he doesn't have the best memory, but still some information so that she feels better.
The tips, the tricks and the cheesy talk is something a guy has in store and that to the store is big. Excessive sweetness leads to diabetes in food and also in life.
Not just some, he has lots of female friends. Now having a friend of opposite sex isn't a problem, the main problem arises when the importance to such people is more than the importance to your girl. That makes her think that you're friends with benefits even if you're not.
He is a mystery for you that you're trying to solve. Whatever he does or he says, nothing about him makes sense at all. You cannot help but think that something is wrong.
When time is something you cannot devote in a relationship, it is a huge problem. It leads to major communication gaps and also leads to doubts in people which they fail to clarify. Noted the fact that you have a life and lots of work, you should in any case find a little time everyday to spend with your loved one.
Every now and then he would tell you that you're wonderful and stuff and will always be like you deserve so much better. That may be one of the reasons he tells you when he will leave you one day.
