Hi all. Wondering if you guys could give me some advise or tips.

Basically, I need to learn to 'calm down', not stress, not overanalyse and take each date when it comes, when I start a new relationship.

I'm a 32 year old guy who has had 3 long term relationships in the past, but lately I find myself in a panic and stressing. I have had a LOT of drama and pain in my previous relationships and I think that is part of it.

I have just started seeing this new girl and I have chosen a girl that is totally different to my ex's. But I'm constantly stressing out over STUPID things and am making things worse for myself. I keep thinking about getting married and spending 40 years sitting on the couch next to her and freaking out. Will we run outta things to say? what if our relationship goes sour in 10 years and things gets messy? What if I stop getting attracted to her one day etc. These silly things are overtaking my thoughts.

Basically, I am stressing out even before the relationship starts. I never used to be a commitment phobe, but I think all my previous drama has caused me to overanalyse.

I guess my main question is... How do I stop stressing, calm down and just take it one day at a time?

TLDR: Dude is overanalysing the start of a new relationship and stressing about future problems before it has even started.
