There is no perfect relationship or perfect match. It depends on how you communicate to each other and manage your relationship, no matter good or bad. Treasure it if it is the relationship you have looked for; learn a good lesson from this relationship if it is not what you want.
Open your mind to know this person and open your eyes to protect yourself. If you noticed something wrong, got to learn holding back a little bit and be cautious about what is going on.
You, remember, are the priority, always.
Good luck, girl.
