it's all not about maths in a relationship in a relationship.

it's not like how much u should get from how much u contributed to the relationship. during the years, the contribution that u mentioned is given willingly, right? if so, should there be any ground to blame at?

and if there's a formula for the "equivalent contribution in a relationship", then we're owing a lot of debts with our parents already ;-)

fully committing urself into work may be a good choice for u now, but mind u about the emptiness that u may encounter. after all u have been living with ur ex for years, so it takes time for u to adapt urself

what's urs will be urs, relationship breakup is generally caused by the difference of personalities or the conflict in the lifestyle or Because of one does not fulfill one's expectation.

just make sure u'll live ur life with no regret, then u'll have my support, TS
