My DH and I (both 35) had a good 5 years before we got married; no huge diagreements and we got along with eahc others' friends and family well enough. On the day we got married, there was an incident which seemed to be only just the beginning of a series of further issues in the months following and by our first anniversary, we were arguing quite badly. We are now 3.5 years in and it has been a shit show of a marriage.
Heavy quarelling of same topics over and over again, threats to leave, issues over wanting to have children (DH changed his mind post marriage), then finding out we have fertility issues so we need IVF, quarelling horribly in the middle of IVF and barely talking to each other (and probably no surprise the round failed) and post-poning further rounds of IVF now.... the list is endless, awful and dysfunctional. We have had loads of counselling for 1.5 years and unsurprisingly, the sessions show we could both be doing things differently/better... but it just doesnt seem to work. We are trying hard but it just feels so so bleak. We are both depressed (DH went on anti depressants for 6 months at one point; I was asked to do the same but declined) and we struggle to cope / function properly at work, life, etc due to our martial problems.
I am nearly 36 and with low ovarian reserve, I am worried I am throwing away my chance at kids if i dont work on this marriage now. Equally i have this horrible feeling that we may end up divorced down the road and whether it is a mistake to carry on and work on the relationship now (to bring kids into it). DH is a lovely man - he is kind, well educated, loves me and cares for me. We just dont seem to be able to agree on anything though and our relationship is full of mistrust and hurt now (we have grown so far apart and are actually scared of each other; we each think the other will leave any moment). My heart breaks to think of the good man that he is and all the good memories - that would all be wasted.
How does one know when one should improve on themselves and work on their marriage; or when its over (and to party ways)?
