Am I insecure or just fed up?

So I am a 24 year old mother of two I have a 5 year old and a 3 year old. My bf and I have a 3 year old together. I know that Valentine’s Day is not the only day to show that you love some one. But if I am in a relationship it would be nice to spend it with the person I love or the person or claims to love me. Every year he always has an excuse it’s oh I’m tired, I’m busy oh it’s not that important. Yesterday I asked if we can go out to eat me him and the kids. He says yes, so I put on a dress some hills and I do the kids hair I dress them up we ready to go. So he tells me he had to drop his sister off, I said ok but I’m waiting a hour goes by I get in my car and say I’m going to go to the bank and get gas. It’s 4 I text him like where are you no answer. So damn near it’s not 6:30 he’s like I had a family emergency. Last week he told me his cousin went to jail but technically that’s not an emergency, his cousin shouldn’t be there selling drugs and there is nothing you can do to get him out of that’s the case he lies so much in my opinion.

But for about a month now we haven’t been around each other. So on Saturday we went house searching we wasn’t even gone for an hour and he says I’m ready to go home drop me off. Of course I’m pissed off cause u wasn’t even with me for that long and the whole time u act like you didn’t wanna be bothered with me.

Another thing too he doesn’t help me with the kids the way he should I don’t expect him to help with the 5 year old because she is not his but at least help with your own. He pays child support and buys her thing but I need a break and I work from home I have a 15 minute break and I use that to get the kids to daycare. I work 7-3:30. It’s hard working from home when you have two active kids. I recently lost my job so I’m playing catch up right now. I can’t even do overtime because of this. I’m tired of having to sacrifice.

I feel like he is cheating because he doesn’t seem like he loves me any more, and I feel like he’s being sneaky and we haven’t had sex in a month and he’s a sex attic do it your not getting it from me than what you doing? He does hug or kiss me nothing. He doesn’t even tell me I’m pretty nothing I changed my hair doesn’t even notice. And he still wants to live together but I feel like I’m falling out of love with him what should I do?
