Hi Ching,
I fully aware of your situation as your story is definitely the same as mine n this doesn't happen solely in a drama. I fully symphatise with you.
Having said dat, maybe you can on your private message so dat i can pm you my email address. I hope i could be of help coz guess it's silly to break up due to family members. Do not allow them to control you, tell them firmly of what you think, if need be, do go for a counseling. As you have already gone for a marriage vows, do standstill with this marriage, talk to your hubby what you think and try to salvage this marriage.
I also went for a break up as your story is sooooo similar to mine, too much interference from the fierce sister, house matter (hubby also a co-owner of the flat with the mum) ,hubby is too filial, dun say anything to defend me, etc. But luckily he stood firm at the end and asked the mum to take out his name. Having married for 3 months now, i would say it is a disaster..haha...coz men and women are just too different and we both have different habits and lifestyle. A couple of times , i want to give it up, but having thought of what we had gone thru, etc, i decided to stay on n surprisingly , my mil whom i reasoned with (i can be quite fierce and strongheaded), was v supportive and i noe all along she's quite wise, just dat i can't stand the sis' interference (like not allowing us to renovate our room tho i had agreed to stay with her)- my mil has a "soft" ears u c..Now, our r/s is getting betta n betta, i invited her for dinner, chat with her over the phone or goes to her home to visit her and talk bad abt his son..haha... Like u , i wanted to give up too coz i feel there are a lot of probs caused by his family members, however i still think it's silly if you allow his family members to be the cause of break up. My advice is do not be influenced by others who advise you to break up,only you noe your situation well, outsiders won't know wat you have gone thru , cool down and try to analyse the pros n cons, talk to the hubby n ask him wat he is going to do with his 'control freak' mum , go for counseling with only 2 of u , then the whole family, i m lucky coz we are a Catholic family so we all went for counseling and try to talk to your mil, why she's doing it, maybe u guys spend too much time together, left her behind, so maybe you shud try to let her join your outing, give her the sense of security that you are not 'taking' his son from her .. at the end, decision is still yours. Hope you can think it over..
