N.B.
This is something that most of us go through when the kids hit middle school.
My daughter had a fit that I "allowed" my granddaughter to "have a boyfriend" at age 13.
I explained to her that they saw each other in band and at lunch, that's it. They didn't call each other on the phone, they didn't do anything after school, they didn't text, they were friends on FB but she hardly ever goes on it. I did invite him to come over a few times to watch movies and to eat but he never, ever, went in her room or anywhere in my house where I didn't have full view of them. I understood the motive and rite of passage that this activity was. My daughter didn't like it but stopped saying things.
The kids are growing in leaps and bounds, then falling back into childhood thought patterns, then progressing again. It's part of that tween/young teen/adolescent growth stage.
In the end she grew a little mentally and realized she didn't like this boy that much and she dumped him. He called her fat and ugly. She was a size 5/6. She decided to like another boy but it was the same thing.
These "relationships" help prepare the kids for future interactions. They need to feel confident and comfortable talking to the opposite gender so that some day they'll be comfortable dating.
I will say that I am friends with 3 couples that had their eyes meet across the bandroom in 7th grade and they eventually got married and have grandkids now. They didn't have perfect relationships with no bumps though, one couple broke up for almost a whole year but realized they wanted to be together. The others were just....meant to be
I tell my granddaughter that the "relationships" she has now are just trial runs, to help her learn what she likes and doesn't like, how she wants to be treated, etc.... I tell her that she is worthy to be treated kindly and respectfully. I tell her that everyone has a bad day now and then, that we take out our anger on those we love because they're safe, they love us and won't turn on us. BUT that there's a huge difference in a boyfriend/girlfriend making snide remarks to us or snapping at us compared to what I would say is abusive or a pattern of disrespect.
I try to teach my girl that she doesn't have to settle and put up with things that make her feel bad. Hopefully she won't find that sort of boyfriend but that I will be there to support her and help her and she won't be alone.
