If he's being at all abusive please speak to Women's Aid. There is no acceptable level of abuse.
Oh I just read your post to my husband and realised you spend an extra 7 weeks away and not 4 (I thought I read you returned on week 7). Definitely too long. My baby has changed so much since, so many milestones. The bonding is so important. My husband agreed that he would have not been happy about it at all but he thinks you must have spoken about it beforehand and agreed it so, if that was the case, he should be OK with it. Still understand your MIL though
It could be so many things but honestly you need to communicate it’s hard enough and you both need to be on the same page to get through it. You’ve been away with the baby & I know men generally have trouble with the bonding also you’ll have your way of doing things now which he won’t be used to. But if you can talk to him to figure out what’s going on with him because honestly you don’t need the extra stress💖
It was his idea to go abroad for the birth as his work is intense and he didn’t think he could give me the support we’d need… and now he’s turning his own idea against me and forgetting he was the one who suggested I do this!
Could it be possible that he resents you from keeping his baby away from him for so long? Obviously no judgement as everyone does what they feel best but I am foreign and my husband is British. Even though my family is all abroad and it was very hard and sad to not have them by my side, I would never consider having my baby there just so I could be close to them and keep him away from my husband. For ages, a friend kept insisting I should go to Portugal with the baby during my mat leave and stay for a while and leave my husband in England in the meantime but, even though he is working, it would not be fair to keep him from spending time with his son. I would have a word with him and explore his feelings a bit deeper as I have a suspicion that could be the cause and I can imagine your in-laws not being particularly excited about that either.
