Sorry to hear about the tingle in your toes and the dizzy spells, it could be from 'withdrawl' I get like that (dizzy) after haven taken pain killers-almost like a hangover...I am not a MD so you should ask your doc just to rule out anything else.
As for your question about our parents, that is interesting, somewhere in another post of mine (no idea which topic, but it was here on DB) I talked about my parents and their marriage. It was the only example I had of marriage when I was growing up, we didn't live near any other family (aunts, uncles, grandparents etc.) and moved every 2-4 years. The main thing I remember from my parents is their loyalty to each other, their committment to the marriage and family. They are still in love and yet both admit their marriage is not perfect and takes a lot of work. They believe in marriage counseling and went to Marriage Encounter when I was a kid, it helped them tremendously. Whenever there was a problem between them, we (the kids) pretty much knew it, they would address the issue (sometimes loudly-LOL) and then work through it. There was always a 'make-up' period. I realize that they still struggle with their issues, nothing is perfect, and like my mom says; 'he may be a butthead sometimes, but he's MY butthead'.
I assumed that my marriage would be much the same. I was wrong. You know what happens when you ASS-U-ME. I had their example to go by and that's what I thought I had. Fidelity and loyalty above all else and committment not taken lightly. I also assumed that H and I would always be able to talk to each other. Got that one wrong too. H talked too little and I too much.
I have learned to accept that my marriage is not like anyone elses and never will be. But that is does have the potential to be what ever I and my H want it to be.
My parents and I are close, we talk openly about a lot of things, they do know H and I are having 'rough times' (no details-don't want them to feel they have to defend their baby and besides I feel it would ruin their relationship with H if they knew) and they asked a while ago if we were getting counseling. They told us it helped them when I was a kid, and how they found their way back to each other because at one point they were thinking they didn't love each other any more.
Unrealistic expectations. That can work either way.
