On setting boundaries

I am relatively quiet and shy and don't say too much when I don't know people. But I'm also very eager to please and try really hard for people to like me. I have always been this way. I am finally, for the first time in my life, standing up for myself. All my life I've allowed people to trample all over my boundaries, and I'm finally changing that. I'm sticking up for myself. And do you know what? It does not feel good.

We have a new housemate who I was very friendly to when she first arrived at the house. I showed her the ropes, made friends with her, tried to make her feel comfortable. This housemate took my kindness the wrong way, and started touching my arm saying "she really liked me" and saying we were soul sisters and best friends and I got really really uncomfortable. I was afraid to confront her and make her upset so I just started to avoid her completely. This roommate then confronted me saying I was rude and hostile. Me? Rude and hostile? I feel so upset by this as the last thing I want to be is rude and unlikable. But it seems that my new boundaries are coming across that way. I don't like it one bit. In fact it makes me feel really upset.

But... I deserve to set boundaries and keep myself safe. So how do I find a balance between keeping myself safe and also not coming across as hostile? I have to figure this out. On one hand other peoples reactions to my actions are not my fault: on the other hand I want to be likable and friendly. Such confusion.

I am not a rude hostile person. I am sensitive and easily hurt, and have, over the years, shut people out to keep myself safe. I guess that has come across as rude and hostile :( but I need to keep myself safe. I deserve, for the first time in my life, to keep myself safe. 

Dinner tonight: I've made veggie lasagna and I hope it turns out well :) last time I made it it turned out really yummy!
