What about HER? Back when they were kids/teenagers, did she want to marry him just as much as he wanted to marry her? How “insistant” was SHE about the rishta?
There could be several explanation for her behavior:
Pregnancy hormonoes
Since she got pregnant right after marriage, perhaps she felt overwhelemed. Marriage already changed her entire life…and then the pregnancy…perhaps for got scared and freaked out.
Perhaps she realized after marriage that she’s not compatible with the guy…and her being pregnancy…she felt trapped. And once the baby was born…she decided to “suck it up” for the baby. Perhaps these days she’s happy b/c mentally, she has devoted herself entirely to the happiness to her son.
Just b/c a couple “looks happy”…doesn’t necessarily mean they are. Looks can be very deceiving. I know MANY couples who seem like the “perfect” family on the outside…yet behind closed doors, their relationship is a complete nightmare. It could be that the wife really had a change of heart and is truly happy in her marriage…OR she may have other motives for staying in the marriage despite not being happy (example: the baby).
