To be honest... it seems like it would lighten your workload if he did disappear to France again for a couple of weeks. 
I totally get that you want a supportive and loving partner to be there to look after you whilst you are heavily pregnant and to support you through labour and to have the opportunity to meet his new child immediately. But I don't think you are going to get that from him. You might find that even if he turns up to the birth that you might wish he hadn't (for instance if he expects you to make sure he's fed and entertained whilst you need to concentrate on you and your new baby).
You need to tell him that you got pregnant on the understanding he'd be more supportive and he hasn't been. That you were hurt that he made the decision not to been there for the birth of your first child and that the stress it caused could have risked the baby and you. Tell him that you expect him to take care of you (by doing his fair share+ around the house and with your DC1) till you go into labour, that you expect him to make every effort to attend the birth and to look after you and your newborn when you get home. You understand that some people find the idea of attending a birth scary or overwhelming and that you'd rather he discussed his feelings openly with you rather than just not showing up.
If he doesn't make any visible effort in these areas, you need to consider if this is the person that you want to spend the rest of your life with and whether you want his behaviour towards you to be the role model you want your children to follow.
So make it clear what you need from him and give him a chance to improve (unless you already feel strongly that the relationship needs to end). But prepare yourself for him not being at the birth and making sure that you have all the support you can get from others.
You and your children deserve better than this. It is particuarly shocking that he wasn't interested in supporting you when you faced pre-term labour. :( In previous threads you have also mentioned that he doesn't even help you look after DC1 - he's not a responsible parent.
Stop making him dinner for starters. You need him to know that it's not okay for him to expect you to do so much whilst you are pregnant. I don't hold out a lot of hope that you will get him doing enough to help, so make sure you get help from others. Take care of you, your pregnancy and your DC1 because you have to, let him take care of himself.
You are being unreasonable to cook him dinner. But you are not being unreasonable to be upset that he is once again avoiding the birth (and will no doubt turn up once DC2 arrives and be sweetness and light again). If he does this to you again, don't forget about it and carry on like nothing has happened, let him know that he has damaged your relationship - perhaps irreprably.
