To fantasise about love

[topa]

I'm not sure if this is weird.
I am in a LTR with 1 child.
I spend a lot of my time thinking of scenarios of this dream relationship with a dream guy. All the little things I'd like, a completely romantic way of meeting, being completely in love and starting a family together... the guy is different all the time and no specific person.
Is this a sign of unhappiness? I should be content with the relationship I'm in given we've already started a family right?
I can't figure out if it's harmless or a cause for concern.

Shameless bump

How romantic is your partner and has that always been the case or has it changed recently? Usually when people fantasise about things like this, it's a sign they want to change something in their current relationship, not that they want to trade in altogether!

Wanting to change something isn't necessarily a sign of discontent.
