I don’t think it’s ridiculous to think a 15 year old is ‘in love’, but I wouldn’t think that they’re ready to make decisions that will affect them for their entire life, or even decisions that will affect the next year or two, based on that emotion.
It’s pretty common advice around here in Utah to not start dating until you’ve turned 16, and even then to mostly date around and group date rather than dating one person steadily.
Pretty much, I’d think you know what love is by then, but you’re not experienced, so you can’t relatively determine how much you love a person. You may love somebody at this point, but since you’ve never been in love with any other people to date, you have nothing to compare it against. Because of this, you aren’t prepared to make judgement on important decisions, like teen sex. In general, I’d just say, WAIT. If you absolutely MUST date, really try group dating or just date several different people.
I don’t know ANY Junior High or Middle School relationships that have actually lasted, excepting one where the girl got pregnant and the guy had to stay with her and eventually get married to her. This couple is anything BUT happy together, they just went to far and can’t get apart now.
Hope it helped
