She 'broke up' with me on our 1 1/2 year anniversary
I'm 18 years old, turning 19 tomorrow and she's 16 years old, turning 17 in about a month. We've been together for a year and a half now and we've been through so much together. I won't even get into that right now.
But two days ago on our 1 1/2 year anniversary, she told me that she's bored of being in a relationship and wants to break up. She says she's not bored of me, but she doesn't want to have to worry about another person right now. She also said that she won't be in a relationship for the next couple of years and that she wants to just remain single. But she's going to wait to officially 'cut ties' with me until next week since she wants to celebrate my birthday with me this weekend.
I'm completely against the break up, but she says that I'm being selfish by wanting to remain together since she's unhappy. She says that us breaking up is not that big of a deal. What gets me is how she says that we will remain best friends and that not much will change. I'll be her 'main rock' and that she won't treat me much differently. She still loves me and always will, she wants to still have physical relations with me, and she thinks that I can be her husband when we're both older and ready to settle down.
How am I supposed to handle this situation? She keeps saying that if I don't take this easier (I've been very emotional the past couple of days voicing my displeasure) that I'll lose her completely and she'll delete all forms of communication from me. I don't know what to do and all she keeps saying is that there's no way I can prevent it.
I can't sleep at night, I have no appetite, I've never been this depressed before in my life, and I can't agree to doing this because it hurts too much. Is it really that big of a deal or am I making it bigger than it needs to be?
