You're early/mid 30s and been with your partner for a few years, living together for most of them.
You ask them if youre the one for them (in a heated discussion) and they say 'erm..I think so?'
They admit they haven't really thought about marriage and then say theyre scared of responsibility and being tied down to one person.
When you explain that because of approaching mid 30s there is a bit more of an urgency to have kids and they say 'You're putting a lot of pressure on me' to you, then go out with their mates 4 nights in a row.
Then when you ask if they could still see themselves with you in a few years from now they can't answer and look hesitant..
They don't seem to be ending the relationship at all themselves, they are 3 years younger which plays a part but still have been living with you several years.
Then they admit they aren't fully happy with you because you aren't as good with money as them and you have been occasionally jealous.
I think staying would have made me a bit desperate? If it's been years and they don't even sound sure then they probably just like keeping you around as a flatmate?
