Going to fast? Relationship becoming a little out of hand? Who do you think is going too fast? I am assuming you think it is going too fast; or that you are thinking intently about your other thinking it is going too fast. Either way, this may apply.
Sometimes, when a person thinks a relationship is going too fast, there may be a few complications in their lives. These complications could be school, work, finances, and simply general life dilemma's. This means alot of problems could be on your mind, and that this person coming into your life asking for love could be troublesome for you since you are not sure of your feelings. Generally, females are more inclinced to this. You may be unsure of your feelings for several reason; or you are using "going too fast" as an excuse.
If you think you are going too fast because you are unsure of your feelings; that is normal. Everyone may come accross this dilemma several times in their lives. It is normal and perfectly understandable to want time to think it over. The best suggestion is to either (whichever you are inclined to) talk to this person more, and find more about them, or take time away from them, to contemplate how you feel without interruptions.
If you think you are going too fast because they keep making suggestions to sex and things you are unprepared for; this is a problem. This person may simply be taking advantage of you and your feelings. If you are in this situation, you obviously have feelings for this person, but you do not want them to be doing these things and wish that they would change. If they did not understand the first time around; then their mindset may not change unfortunately, but that is good for you. If they do not understand, than I suggest finding someone that does.
Sometimes, when someone think a relationship is going too fast, they may be emotionally insecure or aware of their insecurities. You may not be used to having these relationships and it scares you that it is coming along so quickly. If falling in love bothers you and makes you feel uncomfortable, there are other assumptions to be made. It is possible that your family may be not so affectionate, thus, growing up so, you are not used to that type of attention. But this isn't a bad thing, if you are interested in this person, but only afraid of the rush of feelings, then tell them that you need to take it slower. Hopefully they will understand. Also, people who think as such, I wonder.. how would you feel if someone told you that you are a "hot babe"? Good? But how would you feel if someone told you that you are a "beautiful angel"? Cheesy? Hm..
