No not bitter. Like you I look back and there are things i didn't persue because I was in the faith and wasn't allowed too. I loved sports and would loved to have taken swimming or tennis further - big big regret there. I had a flare for drama and loved acting in plays....again I wasn't allowed too. I never fell in love with anyone or got married - witness guys thought far too much of themselves and here in SA it was 7 brothers to every sister - sooo most sisters used to fawn over the brothers, throw themselves at them, .....my nature is not to do that, plus being a little fattie (according to their standards - sure i'm not a size 0) didn't help matters. So no marriage & no kids - which is a blessing as far as I'm concerned.
There is a big BUT here. BUT I am at a much happier place, I'm where I need to be. I'm not too old not to have kids .... though I don't think that will happen any time soon. I have love in my life - not romantic, but it's a pure true trusting love. And who knows, the romantic type of love may be on my cards still. I embrace everything now.
