Constant arguments

[Anx3007]

I need some advice... I've been married for over 15 years, good times and bad.
We've always bickered over nothing sometimes worse than others but we've always got on with it after. I've never felt it was a problem rightly or wrongly as we've always been ok.
The past year or more thats not been the case and we're now at breaking point. We argue about arguing we accept neither person's point if view. We recently came to blows and I'm ashamed to say I lashed out ... I take full blame.
I'm starting to question my sanity that may be I'm to blame for it all. My other half can be incredibly moody I'd say depressive for completely understandable reasons but it also has a huge impact on me.
I'm rambling as I've no idea at all what to do as we try and can have lovely times together but end up arguing.
I don't know what to do anymore

You need to walk away. It sounds very unhealthy and if it’s got physical neither of you is safe so just knock it on the head.

Well if you were a man saying you’d hit your wife the answer would be for you to immediately move out of the family home and I’ll give the same advice to you. You need to leave so that it doesn’t happen again. Find yourself a good therapist and get some help.

As far as the marriage goes, you say you’ve always bickered, and it’s got worse. Its sounds like you don’t even like each other. What’s the point of being married?

How old are you?

It sounds like you should walk away. Doesn't sound healthy & has gone too far.
Focus on healing yourself for a while.
