Would you think this is PPD?

Disclaimer, sorry its long. I would just really really appreciate opinions/advice.

Last Friday night my husband and I got into a fight and didn’t start talking amicably until Tuesday. It was because he passed out on the couch and our son was having a bad colic episode. I felt flustered and I’m sure those who have had babies with colic know how crappy it feels to not be able to do much to help. So I felt flustered and just wanted some moral support/help and literally all my husband had done that day was play video games, eat and nap. But he passed out on the couch. My son started up with the colic and I took him into another room and tried soothing him for about an hour with the crying being on and off. Once that hour went by I just felt flustered as I said so I went and woke up my husband and said “he’s having a really bad colic episode, can you come and help?” My husband being woken up just said whoa and I turned back to go to the room our son was in thinking he’d follow. He didn’t. So I got mad. The second time I went out it was to get the baby carrier (baby wearing) and he was awake and stared at me with his arm out like what??? And he was like is the baby okay? And I snapped. I said no he’s not okay and I woke you up to come help and you didn’t and I just walked away. Clearly flustered and not my nicest moment but not my worst. So I thought okay well now he’ll come because he can hear the baby screaming for sure. He didn’t. He got up and strolled into the bathroom to take one of his 20 min plus dumps. So I was just super pissed at that point. The baby’s next feeding was coming up and I needed to wash bottles and my husband clearly wasn’t helping so I put on my baby carrier once he was sleepy and went out and washed the bottles and when my husband came out of the bathroom he walked up to us and stared for a split second and I guess could tell I was mad and he just turned around, walked away and went to sleep in the office and locked the door. Fight continued on to Saturday morning to spare some length I called him a piece of shit father and he called me a bitching hag. Fun! I apologized Monday and said I’m sorry I snapped this is why I did it but I know it’s still not justified. His reply was I’m not talking about it tonight (after work) because I’m too tired. Which is BS because he’d be tired any night. Even the night he played video games all day apparently! So I snapped again. We didn’t talk about it but we were friendly again towards each other Tuesday and normal on Wednesday.

Fast forward to today, I ask him to text me when he’s leaving work because I’ll start dinner so it’ll be ready when he gets home then. He texts me he’s leaving, I start dinner and finish it. Then when 50 mins go by since the he’s leaving text I call him because he works 25 minutes away. In my head I’m like he stopped at his mom’s again - I have issues with his family, they’re a trigger for me - and didn’t tell me. So I call him and expect him to tell me he stopped there but instead he said he’s almost home and I say was there an accident or traffic and he’s like no people are just driving slow. Mind you, he works only 25 mins away and I mapquested just out of curiosity and there was no reported traffic. He literally got home a little bit over an hour later and my mood is just shit again. I feel pretty confident that he lied and went to his mom’s. Which bothers me (I haven’t told him though I let it slide) when he does that instead of coming straight home to see his baby. But again he doesn’t know I feel that way because I’ve hidden it and it’s only happened about twice before. But this time he’s lied about where he was. Again, I’m not 100% sure he was there but I’m like 95% confident. Why would a 25 minute drive take 70 minutes when there’s no traffic?? Anyways, I basically lost my appetite for dinner because between the earlier fight and then him lying (I believe) I just feel like shit. I feel like he doesn’t give a fuck about our marriage. And I have trust issues already and him lying makes them that much worse.

So if you’ve made it through - sorry it’s a novel - would you say that how I’ve been feeling would fall under the PPD umbrella? Please be kind in your replies, I know I’m not perfect. I have anxiety and trust issues.

*Also he’s lied about giving his sister $500 when I asked him if he did before so he does have a history of lying when it comes to his family. When we got into a fight about that he said it wasn’t lying because he didn’t “give” her the money he “lent” her it.*
