New relationship worries

Current model:

C: New Relationship
T: What if it doesn’t work out?
F: Anxiety
A: Overthinking, overanalyzing
R: Anxiousness

C: New Relationship
T: Thinking about all different things that we could do as a couple am I setting expectations too high – setting myself up for disappointment
F: Anxious
A: Try to get on with work and not be wondering about what he is thinking or doing if he doesn’t get back to me right away
R: Still low level anxiety
C: New Relationship
T: I’m not sure where this is going to go but either way I’ll survive
F: Still nervous
A: Be myself but try not to expect too much
R: Hopefully things work out for the best
Not sure why I have such a difficult time just living in the present. I’m always worrying about the future – will it work out? Will the kids like him? Will he like the kids? Should I introduce them sooner than later? He seems to be less established than I would like but I still love his personality and we have fun together but am I setting myself up to be struggling later on? I’ve been waiting for this ‘white knight’ to rescue me but I always seem to be the one that does the rescuing – will I ever get a break, will I ever have someone I can depend upon? Why do I have such a hard time relinquishing control? everything always comes down to that last one – Why am I so afraid of losing control? but I don’t have an answer for it. I don’t want to be perceived as vulnerable, weak. Why do I care so much about what other people think? Why am I always looking for outside validation? I know there’s a lot here and I’ve done models but I just can’t seem to get past these.
