So I've posted a couple of times previously and you guys were really helpful, I'm hoping to get some clarity & more than anything so desperate to feel well not worthless anymore.....

Me and my ex partner were together for nearly 15 years. A week ago, he told me he didn't want me anymore and that there was someone else - she's someone he's been working with for 6 months & talking to online for about 10 days - she's 21 years old.

The week prior to the break up, we were having sex and actively trying for a baby (he was initiating it). Things seemed fine & intimate and I never suspected a thing. We've had our problems over the last 3 years mainly due to money, they have been my issues ive never been able to get a hold on my money handling & I used to help my family out - putting us in jeopardy but we got through it. Money has always been a worry with me, something that seems stupidly easy now.

But throughout our relationship, I've never been his top priority. I literally lived for him, I was constantly making sure he was ok and we had a lot of arguments about him not making an effort with me. He knew I was always there, so he didn't have to try and in all honesty i am an insecure under confident woman - though this has always been the case.

We have shared some amazing memories, we have a close group of friends and we've been solid - the laughter and the amount of love we've has made all the troubles worth while - so how can he go from all that and trying for a baby with me one week, to not wanting me & being so cold the next?

Im really struggling to understand how 15 years meant nothing to him, hes so matter of fact about everything. Hes speaking to this girl on the phone every day as well as messaging her, stuff we used to do. How is a 15 year relationship, that replaceable?

I am in absolute tatters and hes acting like this is a normal breakup, he went behind my back and ended it and suddenly has no feelings in 1 week. I cant bare the idea that I meant nothing to him and now I'm just a stranger to him, i gave half my life to him & hes just stamped on it like it was nothing.

I cant help but picture them together and I dont even know this girl, how can it happen so quickly?

Did I really mean nothing to him? Theres so much I dont understand, my heart is broken....
