At what stage should you know whether a relationship has a future or not and would you stay indefinitely?

[xela21]

When do we think most people know whether their relationship has potential / they want to be with their person long term?

Would there come a point when you leave if this feeling wasn't achieved, if so when?

Am I happy ?
Do I feel this person enhances my life ?
Do I enhance his ?
Do we have fun together?
Similar interests ?
Same goals ?
If any of that becomes a no ... I'm probably out ..

Am I happy ? Content, some happier times, some less so.
Do I feel this person enhances my life ? Provides companionship, someone to do things with on weekends, someone to care about and be cared by etc.
Do I enhance his ? As above
Do we have fun together? Yes
Similar interests ? Some.
Same goals ? This ones hard to answer, not sure if one(/both) party has thought much about goals.
If any of that becomes a no ... I'm probably out ..

If you both talk about your future together, you find it easy to talk to him, he is someone to rely on and his actions matches his words.
Any sign of being let down or not being able to agree on important things would be the time to walk away.
