From ttc to saying goodbye

So my a significant other who i really thought i would end up marrying broke up with me. We litterally went from ttc baby #2 to end our whole relationship for good in a matter of about 2 1/2 weeks. We had alot of issuses and i thought about going on a break more than 10 times but never did i think we would completely end it the way we did. Its super weird and sad bc we live in the same house. Im about to go from a sahm to a full time working single parent. My # 1 priority is my 8 month old son. Ill get thru this tho
