I've been talking to this guy and we fought our feelings for a long time (he Is going through a divorce) but we couldn't fight them anymore. So we have been talking and things progressing but I've been very patient and understanding of the process he is in and how until everything is in writing official for his kids we aren't creating any waves bc his kids are #1 priority in this of course. Anyways it progressed mainly from him I've been following his lead on this progression. Well he started talking about once it final our future together how he wants to be with me how we are gonna make our households work together...how this work with his kids and my animals ... if I'm okay staying in this area til kids grown like we been really in the thick of discussing this I thought in a healthy way.... well this week was his first week away from his kids ever and on top of that he is starting a new job next week which he is stressed and overwhelmed with and I've been understanding about that I also have a new job starting this week that I'm completely in over my head witb bc im being forced into this position with no incentive and alot more on my plate and im extremely stressed.... well this week we got in a couple little tiff but I thought we were working through them bc we both so overwhelmed. .. we were good talking hugging loving each other when suffenlu he decided we have to be done ...he can't do this to me anymore ... this has to end I kept asking him to just tell me what happened he said it's bc of our little misunderstanding (thst we had already cleared up) and how he doesn't want thst to happen again he afraid I'm gonna hate him bc of new job etc and it has to be this way .... I was bawling and he just left me and drove away the next day we talked I realized mistakes I made and talked them out I thought we were okay again and then bam same thing and im like I don't understand please just help me understand what I did here ... he kept saying he didn't want this but it has to be like this .... and im like I promise u this isn't how this has to be...he told me Thursday he just needed time to process he would contact me Friday I asked him if he was just saying that so I would drop it he said no he truly meant it he promised he contact me ... so I let him go he never contacted me and I found out he blocked my number and everything. ....
