I don’t know what to think

My boyfriend and I have been together 5 1/2 years now. We have 2 kids 3 1/2 year old and a 1 year old. Lately things have been a little tense. He has always been the one to pay all the bills, I’ve worked on and off part time to stay home with the kids. Right now money is tight so we’re both stressed. Saying “I love you” is something that he’s never really said so I don’t say it to him either. Lately hes been coming home and getting mad if things aren’t cleaned up and just the way he wants it. The kids and I had a nasty stomach bug last night and we were recovering today. He got home from work and I hadn’t cleaned up the house (obviously.. I was sick) and he started slamming things around and throwing things that were in his way (throwing meaning tossing aggressively). He acts like that whenever it’s not picked up. If the kids toys are on the counters he’ll throw them on the floor and set a bad example instead of just asking our daughter to put them away. I’m not sure how to feel about all of this or what to do.

Like is this aggression the beginning of something and it’ll turn into something abusive? We’ve been together so long and have so much together. I don’t want to stay together just for the kids and I do love him. But I don’t want to be that woman who doesn’t see what’s going on and is blinded by love. I don’t know if all this is just because of the stress. I just don’t know! I need an outsiders opinion 😩😢
