As a mother you never should feel too involved, it's your job to make sure that you know what's going on with your son and it's awesome that you are kinda close with her mom. seems like a lot of your values are the same which means each family knows what to expect from the others and the kids are less likely to come up with a scheme, and get one of you.
That being said I had a boyfriend when I was 15. He lived a couple towns away and I didnt have a drivers license. His mom worked in my town so she picked me up, and my boyfriend took me home. His family was very supportive and I became part of the family. My family liked him , but their guard was up " She's only 15, she can't fall in love!!" etc. etc. etc...... Well guess what?????
I fell in LOVE with that boy and eventually he turned into a man, and me a women. We bought a house, got married (after 7 1/2 yrs dating) And now have 2 beautiful boys of are own! He is my bestfriend, our relationship only gets better, aand I go to bed every night thanking god to have found my man in the moon! I also love his mom as my own. She was always so suportive, and I could confide in her with anything. Don't get me wrong there are times she drives me nuts, but I think that happens when your so close. Plus If it wouldnt have been for her raising suh a wonderful caring goof ball, Maybe I still might be searching for the "One"
Love is not something that can be created, I don't care if your 15 or 50, when you experience it, there is no way around it. I would rather be with my first love, then to have broken up and dated around. I never felt as If I were missing out, more grateful to know I LOVE him, and he LOVES me, and we don't give up on one other, we share everything and trust each other 110% because the respect we have for one another is a priority.
We have made it being together almost 13 years and will be celebrating our 5 year wedding anniversary this year!! You never know where your heart will take you, so don't be to easy to judge it as just a little young romance :)
