Story:

So we have been dating for a year and a half now. We used to be together all the time, had fun, travelled during the summer, etc. We were always together with her family and my family, you know, we had a healthy relationship. Now for about a month or two, she has been kind of ignoring me, I could say. She doesn't text me a lot, doesn't call me AT ALL anymore. She doesn't want intimacy anymore, we don't have sex anymore. It wasn't a problem before, we used to have sex, play together, get intimate, etc. Now even me touching her legs gets her irritated and *she claims she is not ready for intimacy yet, and that she is too young for it*. KEEP IN MIND: we used to have all this! When I asked her why she used to have sex with me and now claims she isn't ready, she says she didn't realize it until now. NOW. YES, I know, sex isn't the main part of relationship, and YES, I am 15 and she is 16. That's not the point, the point is that she doesn't want to be together a lot anymore, she said she is bored and wants a break for 2 weeks. And I believe her, I do. But what I don't understand is that, she used to miss me after not being together for 2 days already, and I still do miss her all the time, it looks like she doesn't though. What can I do to spice the relationship up? Or if I can't, should we break up or should I wait until she gets the 2 week break done and see what happens?

It sounds like she has matured and you have not. She has come to realize that 16, and 15 is too young to be having sex, and ending up with a baby. (no birth control is 100 percent)

So, she is asking you, to change the relationship to an emotional one, that most 15 year old boys have no clue about. You are wanting "spice" and sex and she does not.

So you.
Stop trying to have sex, explain that you will try and have a close emotional relationship without sex. (if you are willing to do this)
If she has not already given up on you, she may see if you can be committed.

Or break up with her and find another girl that has less respect for themselves and will have random sex without worry about the future.

When the lust fades, you find out what you really have going for the relationship. The partners that cannot adjust to those changes of feelings seldom stays together long, even if one partner doesn't want things to end. I think you start preparing for the worst case, a break up, since you are already on a break, and she obviously has been thinking of this for a while now.

Young teen age love/lust never lasts that long anyway (even most adult relationships don't last that long either), and you should be grateful for the good times while it lasted. Even when you know and understand that's the way love goes, it still sucks for a while though for sure.

Not a lot of options when one partner decides to end it, and crying and begging seldom helps at all either. Best keep some dignity and self respect and thank them for the good times when you get dumped, because it was fun while it lasted.

Actually your ages are the point. You are two teens and as two teens you both have a ton to learn.

Girls mature faster than boys. She is older than you and. Is maturing.

Maybey she realizes that. There is no form of birth control that s 100% effective and she isn't ready to be a mother.

She he may be focusing on her future.

I like to say that teenagers 'change on a dime,' but now that I think about it, many adults do too.
In adults I'd call it being fickle and irresponsible - dumping your wife for a younger woman after 10 years and 2 small children.
But in teens, it's just the incredible growing that is going on, and you can't be expected to feel or think one thing one day and the next.

PS: Although you and all of us may believe her about the 2 week break, please don't count on her wanting you back. It rarely happens. She probably doesn't even know it yet.
PPS: I cringe when a teen says 'she doesn't text me a lot.' Nothing strikes more terror, more wish to run, than the thought of someone texting every inane thing all day and into the night. It's the number one characteristic of clinging immaturity.
