The break up

I've never had to break up with anyone. I hate the text messages people send each other "it's not you its me" no closure in that. I know breaking up via text message is the worst but sometI'm es it's

These past couple of months have been so hard
We've been together now for a year and half
I am grateful for all that you have done for me
You have been there for me emotionally, physically and financially
You've made me smile laugh and cry
And when i'm with you I get so lost in this bubble that we have created for ourselves, our happy place.
I know sometimes I can be difficult and closed off
My way of dealing with things is by shutting down
I am terrified when it comes to opening myself to anyone
All I am, all I feel and all I've lived I've kept buried deep inside
You always ask me to share with you my pain
But I am so scared to share it because that's what makes me me
I'm scared if I share it there will no longer be my secret I'm afraid of feeling free....
You make me happy but I'm not happy with me
I am at a stage in my life were I feel extremely insecure
No matter what I do and how hard I work nothing seems to be paying off
My efforts and hard works and going unnoticed
I'm frustrated with everything
As time passes I feel like I am going to start taking all my anger and frustration out on you and I don't want that to happen
I don't want to be in a relationship if I'm not contributing or not bringing anything to the table
I don't want to constantly be reminded of how much you do for me and how I wouldn't be anything without you
Maybe it's my pride, or maybe I'm just being realistic.
