Experimental data for ${}^{6}\mathrm{He}{+}^{1}\mathrm{H}$ elastic scattering and the two-neutron transfer reaction, measured recently at the Joint Institute for Nuclear Research in Dubna, Russia, were analyzed by coupled channels calculations using a dineutron model of ${}^{6}\mathrm{He}.$ The results of the analysis reveal that all the processes induced by ${}^{6}\mathrm{He}$ on a hydrogen target are coupled. This analysis shows that the couplings to the ${}^{6}\mathrm{He}\ensuremath{\rightarrow}\ensuremath{\alpha}+2n$ breakup channels can be included in a simple optical model calculation by means of a polarization potential that is repulsive and whose strength is about 25% of the single-folding potential. Predictions for the ${p+}^{6}\mathrm{He}$ inelastic scattering to the ${2}^{+}$ resonance are made. A good description of the two-neutron transfer reaction data is obtained when the triton transfer process is coherently added to the dineutron transfer. The spectroscopic amplitude of the $t+t$ component of the ${}^{6}\mathrm{He}$ ground-state wave function is found to have the opposite sign to that of $\ensuremath{\alpha}+2n$ with a magnitude close to that predicted by a microscopic four-cluster model of ${}^{6}\mathrm{He}.$
