We may have to postpone our wedding indefinitely (it's a long story sorry)

So I have had a pretty ironic day today. I was out of pregnancy test and it's getting to be about time to take one. My birth control stops my periods so in the last almost 3 years I have had exactly two periods. Because of this I take a test every 6 weeks or so to make sure I'm not pregnant I know it's not really necessary but I do it for my own piece of mind. TH and I are not actively trying to conceive so we hope for negatives for now. Anyways back to the point. While I was looking at pregnancy test I had just grabbed a box when my boss came around the corner and started talking to me. We work in a hotel and I was not expecting to see him at a store especially since he was scheduled to be at work within 15 minutes from the run in. I know it's not a big deal but it was awkward and I wasn't about to explain to my boss my reasoning behind choosing one brand over the other so I kept the brand in hand and checked out. Then I did what I do every morning after work I stopped by my grandma's house and while I waited for her to get back from taking my niece to school I found a letter from child services addressed to me. My cousin has had all three children taken away and they are looking for a relative to place them with. The fact the kids were taken away is not at all surprising when their mother was 16 and pregnant with the first one I said it would only be a matter of time until child services got involved. Well the first time they got involved was when the mother was pregnant with the second one and the oldest had managed to dump boiling water on herself and had 2nd and third degree burns on over 80% of her body. Since I cut contact from that side of my family long ago I hear everything through the grapevine from my grandmother. I do know child services has been involved several times since then. The final straw as far as I know was when the mother failed a drug test after having the third baby. I was told that the baby was taken away when it was 8 days old. She will be two months next week. If these children are in need of a permanent placement we are discussing how we may be able to do that since it would require a major shift from replacing our house in 5 years to having to do it immediately. Our house is in no way shape or form ok for a child much less three. It is fine for us adults as we can do what needs to be done to keep warm despite the fact you can feel the wind when your inside. We originally planned on fixing it up but it would cost more to do that then build a new one instead. There are other financial considerations as well including the fact that my current car which is less than a year old is too small to fit three car seats. Now we are perfectly so trading in the car and moving up our time table for rebuilding the house however, We can not in good conscience do that if the placement would only be temporary. Additionally we would go from just the two of us to suddenly having three kids ranging from 2 months to 4 years. We would also have to buy them literally everything they need to live including shoes, clothes, beds, car seats everything. Financially something has to give and that would be the wedding and honey moon. If we take on these three kids we will have no other choice but to put off the wedding indefinetly.
