Are you a single parent, OP?
I ask because i am, and my DS- who is only 4- is literally the clone of me in manner, looks, temperament etc. and even now I can see the bond I have with him is different to the bond my sister has with her children of a similar age. Some of it is the single parent thing I’m sure, and some of it is that he turned out to be me in miniature. (Not necessarily a good thing
).
I recognise that this has the potential to become unhealthy/codependency as he gets older (from my own experience with my mother), so I am very very careful to maintain parent boundaries rather than “mates” vibes. Easy at 4. Not so much at 24.
And I’m definitely not always getting it right. I give him too many opportunities to make decisions, for example. That’s okay now- “do you fancy pizza or pasta for tea” isn’t going to end the world- but I know unless I sort this out, in 10 years time, I might well be having debates with a teenager about drinking or smoking or staying out all night, when he should be just complying with my rules.
I know from my own experience with my mum, that what kids want- at any age, 4 or 24, - is a parent who sets firm boundaries, represents safety and security, can be depended on and who doesn’t need their child for emotional support. I’m 33 and I still wish now I had that kind of mum- so that’s the kind of mum I’m trying to be.
It’s late in the day now for you to alter the calibre of your relationship, but maybe some joint therapy would help you both to externalise how you feel and make sure you’re keeping mentally/emotionally healthy in your relationship?
But don’t feel bad about the soulmate thing, OP. It’s not synonymous with romance- that’s just what the rom coms tell you. My dearest friend is a gay man, and is 100% my soulmate- no lover has ever come close.
